It seems to me that the discussion has things backwards.
It was the Starfleet members who had reason to be angry at the Maquis, not the Maquis who had reason to be angry at the Starfleet.
The war (or wars) between the Federation and the Cardassion Union apparently lasted for years and was apparently a small scale frontier skirmish for the Federation - nobody mentioned that there was a war with the Cardassians during the first seasons of TNG. But it was probably a much bigger deal for the Cardassians than it was for the Federation.
Becasue after the war was over, the border of non Cardassian space reached deeap into the former space of the Cardassian Union.
The Cardassians had to grant independence to, or cede to the Federation, a lot of formerly Cardassian ruled planets. Persumably the Federation annexed all the Cardassian military bases and Cardassian inhabited colonies in that zone, no doubt allowing the Cardassian colonists to emigrate to Cardassian space if they wanted to, while requireing that he Cardassian Union grant independence to every planet and system with native intelligent life in that zone, so that every single system in that zone would now be either indpendent (withe he option to join the Federation in the future without any Cardassian objections) or Federation ruled.
Not doubt the Cardassian Union expanded outward in all directions from Cardassia Prime in an ever enlargening spherical shape. Until the Federation war (or wars) resulted in the Federation annexing or setting free from the Cardassians all solar systems in that zone I mentioned.
And as far as I can tell, that zone of space would have been at best, a narrow cone of space including many solar systems pointed like a daggar at the heart of cardassia, Cardassia Prime, the Cardassian homeworld and capital planet, and at worst it would have been an entire hemisphere of the former Cardassian Union, half of all the former Cardassian space and worlds.
No doubt the Cardassian military tried to violate the peace treaty turns and keep possession of Bajor as a defensive position in any future wars with the Federation, until the Federation pressured Cardassia into evacuating Bajor, leaving Cardassia Prime even more vulnerable to any future Federation attack.
It seems pretty obvious to me that Bajor and Cardassia must be near neighbors as interstellar distances go.
For one thing, in "Explorers" Sisko built a replca of a 800year old Bajoran spacecraft:
SISKO: Here. Look at this.
(Sisko shows Jake a PADD with a blueprint on it.)
JAKE: What is this, some kind of ship?
SISKO: According to legend, the ancient Bajorans used ships like these to explore their star system eight hundred years ago
JAKE: You mean that when humans were first sailing across the oceans, Bajorans were already going to other planets?
SISKO: Some scholars say they made it all the way to Cardassia.
JAKE: That seems hard to believe. What are these?
SISKO: Solar sails. These ships were propelled by light pressure.
JAKE: Like a sailboat catching the wind.
SISKO: Exactly.
JAKE: I wonder if a ship like that could really fly?
SISKO: I don't know. That's why I'm going to build one.
DUKAT [on viewscreen]: I understand you're planning a trip.
SISKO: Word gets around.
DUKAT [on viewscreen]: I can't believe that a man of your intelligence would take stock in Bajoran fairy tales about ancient contact.
SISKO: If you recall, you thought the Celestial Temple was a Bajoran fairy tale, until we discovered the wormhole.
DUKAT [on viewscreen]: I suggest you reconsider your plans. Solar vessels are very fragile, and it's a long way to the Denorias Belt at sublight speeds.
SISKO: Don't worry. I'll have emergency equipment on board. If something goes wrong, Major Kira can have a runabout to me within an hour.
DUKAT [on viewscreen]: An hour can be a long time, especially if you happen to encounter something unexpected.
And when Ben and Jake set out in their solar sailed Bajoran ship:
QUOTE] (Big crash.)
JAKE: What was that?
SISKO: I'm not sure, but whatever hit us almost tore off the port mainsail.
(The stars start streaking by in a familiar way.)
SISKO: Main power's offline. We're moving at warp.
JAKE: How can that be?
SISKO: I don't know.
(And it stops)
JAKE: What happened?
SISKO: That's a good question. (checks the star chart) There's no record of any spatial anomalies in this region.
JAKE: What are these?
SISKO: Tachyon eddies. They run all through this area.
JAKE: Could we have gotten caught up in one?
SISKO: No, tachyons don't have enough mass to affect a ship of. This isn't an ordinary ship. It has a lot more surface area relative to its mass.
JAKE: Because of the sails.
SISKO: And since tachyons travel faster than light, it could be that their impact on the sails somehow accelerated us to warp speeds. We could be light years off course.
JAKE: The question is, where did we end up? [/QUOTE]
Later Cardassian ships arrive at Ben and jake's ship:
(Comm. beep)
SISKO: Looks like we're about to find out. What can I do for you, Dukat?
DUKAT [on screen]: Well, I wanted to be the first one to congratulate you.
SISKO: Congratulate me?
DUKAT [on screen]: On managing to make it all the way here.
SISKO: All the way where?
DUKAT [on screen]: Don't you know? You've just entered the Cardassian system.
JAKE: The tachyon eddy. It must've taken us past the Denorias Belt and brought us here.
SISKO: The same thing must've happened to the ancient Bajorans.
JAKE: We did it! We proved the trip was possible.
DUKAT [on screen]: I hate to interrupt your celebration, Commander, but I've been asked to convey a message from the Cardassian Government. (reads) Your voyage is a testament to the spirit of the ancient Bajorans who first ventured out into space. It could not be more appropriate that your arrival coincides with the discovery here on Cardassia of an ancient crash site, a site that our archaeologists believe contains the remnants of one of the Bajoran vessels whose journey you have just recreated.
SISKO: What an amazing coincidence.
DUKAT [on screen]: Yes, isn't it. Welcome.
(The Cardassians put on a 'fireworks' display for them.)
So if the tachyon eddies take Bajoran ships from the Bajoran system to the Cardassian system instead of too other solar systems, those two solar systems must be really close by interstellar standards.
Furthermore, the
Star Trek: Deep Space Nine Technical Manual 1998 states that Bajor and Cardassia Prime are only five light years apart.
According to Star Trek: Deep Space Nine Technical Manual, (p. 3) the exact distance between Cardassia and Bajor was 5.25 light years. According to a stellar cartography map on the same page, Cardassia was located in the Bajor sector. [1]
In
2375, the location of Cardassia was labeled on a tactical map that was displayed in the wardroom of
Deep Space 9. Cardassia was located approximately five
light years from
Bajor, thirty light years from
Starbase 375, and fifty-five light years from
Ferenginar. (

So cardassia has literally no defenses left beyond their home system against any future Federation attack on Cardassia Prime. The Cardassians could only have agreed to such terms in the armistice and the peace treaty if they had no choice, as a last ditch effort to prevent a Federation fleet from attacking Cardassia Prime.
So the minor border skirmish with the Cardassians from the Federation point of view must have been a disastrous armageddon from the Cardassian point of view. The Cardassians were crushingly defeated.
So it seems reasonable for all the Federation colonists living along the former Cardassian border to rejoice at the Cardassian defeat and their freedom from any fear of Cardassian aggression in the future.
It seems to me that only a tiny percentage of the Federation colonies near the Cardassian border had any problems with the new treaty borders. Probably the Federation surrounded the entire former space of the Cardassian Union, making it an enclave within Federation space like san Marino within Italy.. Once the cardassians had expanded to the limits of federatin space, there was no where left for them to expand to, and no doubt one of their reasons for the wars as an attept to break through to spacebeyond the FEderation.
And quite possibly the Federation granted some Federation colonies to the Cardassians - as various episodes show that they did - as a partial compensation for all the planets which the Cardassians had to give up. And those planets would have been on the side of the cardassian union which was farthest frm the center of the federation. So the Cardassians could now expand into unclaimed space, but only in the difrection leading away from the main centers of the Federation and away from future conflicts with the Federation.
But that would be only in a small sector of the Federation-Cardassian border.
The Federation colonists on the planets that were ceded to the Cardassians were citizens of the Federation, and owed their highest loyalty to the Federation. The entire Federation was their home, not merely the Federation-Cardassian borderlands, and not merely the one sector of the Federation-Cardassian borderlands which were ceded to the Cardassians, and not merely the individual systems and planets they lived on.
In the USA there is a law of eminent domain. Federal, state, county, and municipal governments can seize the property of private citizens, paying htem fair market value for that property, to serve public purposes. The property where I once lived was seized by the local school board and is now a school parking lot. So no doubt the Federation offered the colonists on the ceded planets fair prices for their property and payment of their expenses to move to other planets.
And any colonists who turned down such offers to say on the planets ceded to the Cardassians, risking various conflicts with the cardassians, would have been recklessly risking the lives of their families and friends who they may have persuaded to stay, and were recklessly risking increasing tensions with the Cardassians and making a new war with the Cardassians more likely.
And what gave those small groups of stubbon colonists the right to risk a future hellish war in which the total number of persons killed might tens, or hundreds, or thousands, or maybe even millions of times as great as the total number of colonists affected by the peace treaty?
And as a matter of fact the Maquis did cause a lot of trouble with the Cardassians, and no doubt many Cardassians believed the Federation was secretly backing the Maquis. And eventually the Cardassian anger at the Maquis may have been one of the main reasons for Cardassia Joining the Dominion, and for the outbreak of the Dominion War in which Starfleet suffered several casualty rates and the Federation often seemed to be on the verge of total defeat.
So it seems to me that after they learned about the outbreak of the Dominion War, the Starfleet members of Voyager's crew had a lot to be angry at the Maquis about, considering their them largely responsible for the disasters of the Dominion War.
