They didn't drop it the Maquis thing, they just had them logically realize it would be stupid to hate one another when they had bigger problems and whatever other minor issues they got over as time went on. They just didn't shove it in our faces 100% of the time.
This isn't even about hating one another. This is just about setting up a plot point and then doing very, very little with it. As a distinct identity the Maquis were basically gone by the third season, and the consequences of their identity in the first two seasons was minimal. Their biggest role was an excuse to include more deviant characters in the crew - the unorthodox, insubordiant bunch in "Learning Curve", psycopaths like Lon Suder or traitors like Jonas. When it comes down to it Seska played a more major role in the series arc and stories than the Maquis did.
If you want a comparison with DS9, here's one: The Bajoran Militia. They don't hate Starfleet, but the Bajoran Militia are a recognisably distinct group and the tension was exploited occasionally - and early in the Dominion War, it was crucial because Bajor was neutral yet the Federation was not. There are also some intellectual differences - Bajorans are by and large religious, while Starfleet is very secular. So one could get episodes like "In the Hands of the Prophets" which played on this distinction in a meaningful way. Lon Suder might kill people but he just did so 'cause he's
crazy - he need not be Maquis at all, really - but Neela did so becuase of her Bajoran beliefs.
An obvious example of what the haters would consider VOY's main flaw is that it existed, and that it wasn't a DS9 clone. Nothing else would have placated them.
Again you're dealing with an amorphous they, a bunch of straw-men.
Even if such people exist, it's probably more productive to argue with people who think Voyager could have done better rather than feel Voyager could not work at all.
So, rather than cite 'but X would
never be happy with this!' just address folks like me who are actually posting here.
Pretty much, they did. VOY was getting trashed the first 30 minutes of Caretaker while DS9 and BSG got free passes.
That's not true. DS9 took a
lot of flak in its first season. 'The Shopping Mall to the Stars' stuff, jibes about it boldly standing still. It'd be fair to say the series was looked down on by a lot of TNG fans, which is part of the reason TNG's impressive viewing numbers didn't transfer over to DS9.
Going a bit later than that? Well, there are quite a bit of season seven twists Niner fans don't like and aren't comfortable with. I for one never really liked anything to do with the pagh wraith arc, except maybe beyond that episode with Keiko getting posessed... and Dukat's devolution in that year was depressing. DS9 is far from a flawless series, and heck, any series that took a couple of years to find its feet and 'get good' has some implicit issues.
BSG has also taken quite a bit of criticism over the years, particularly for how the later seasons and finale turned out. I haven't watched the series so I can't comment on that in greater detail, but it seems that a lot of the stuff that happened then did not sit well with many of BSG's fans at all.
I outlined just why they didn't like VOY: For Voyager's "problems" to have been solved (in the eyes of a Niner) the entire crew, with no exceptions, would have to have completely fallen to pieces within the first two episodes and spend the entire series hating and plotting to murder one another.
Come now. That degree of character conflict didn't even happen in DS9. I'm sure Niners would have been happy with, well, the level of character conflict they got in DS9!
