The general level of analysis is pitiful. I've been skipping around because it's not rewarding reading, but this at least tries for a little more honesty.
1. VOY didn't have the epic/dramatic scope pioneered by DS9, which caused many to see it as a regression.
2. VOY did not have the benefit of being the main sci-fi show (or Trek show) around as TNG did, which made it easier to overlook the latter's faults and harder to overlook the former's.
3. There was a little Trek fatigue, which is why the creators had wanted to delay the start of VOY.
4. There *was* some network meddling, as with TOS.
5. Jeri Taylor nixed a lot of stories because she wanted it to be more like TNG.
6. There was a lack of continuity (though I think it's a little exaggerated. It just stands out more because of DS9.)
7. It was trying too hard to appeal to a mass rather than Trek/niche audience, which made it highly episodic and often more comical than was probably necessary.
8. Fans who actually paid close attention (understandably) grew frustrated with the always-pristine condition of Voyager, despite its severance from SF.
9. Character development wasn't a priority. Many say that's what made DS9 compelling, and how Piller explains he helped "rescue" TNG when he joined TNG in season three. He said he didn't know sci-fi but he knew how to write characters. Piller was only around for the first two seasons and was a lame-duck, so he didn't fight hard to get his ideas accepted (so he says).
10. Seven's arrival was rather controversial for a number of reasons. And many were displeased as it gradually became a trio show focusing on Seven, the Doctor, and Janeway.
11. Some stories were rather poor quality.
12. Many things didn't quite make sense, such as how the primitive Kazon followed Voyager for two years (and away from their home territory).
13. The frequency of Borg episodes was controversial. The Borg were highly popular, especially to the casual fan, but some suffered from "Borg fatigue". The Borg were also portrayed differently with vendettas etc.
1. Apotheosis, space war, empires falling, etc. Space opera, in other words. I like me some space opera too but if they wanted more DS9 they'd have been better off making more DS9.
2. In other words, competing with DS9 made it look bad. If you say so.
3. The Star Trek vision of the future has its roots in the Sixties. Of course it's getting out of date. There's no reason to think it's any truer of DS9 than Voyager.
4. Since Voyager was on UPN, it certainly had more network meddling than a syndicated show. That's given. Shocking as it may seem, sometimes the suits are right. As near as I can make out, it is controversy that brings out the worst in them. Ditching Chakotay's electronic hallucinator religion was the character's last chance for a real contribution. And Chakotary wasn't a Neelix or Kim, his dramatic weakness hurt the show.
5. Less like DS9, in other words.
6. No, Voyager wasn't serialized like DS9.
7. This is pretty much the same thing, except it thinks doing comedy is a bad thing. If you say so.
8. This is incredibly stupid. I've seen posters talk about patched up ships!

Just because someone lacks the sense to wonder where the patches are going to come from (floating by in the interstellar void?) doesn't mean they should be taken seriously. Again this is an incredibly blatant double standard. There's no way Voyager's replicators are any sillier than TNG's or DS9's. The whole notion of hardships is and was ridiculous. But people say they wanted
more ridiculous? This is too crazy to be true.
9. Again, this is saying, not DS9. DS9's notion of character development is turning Sisko into a god, Odo into a god, Bashir into a superhuman, Kira into whatever seems cool, even a kind of Jewish stepdaughter to Hitler!
10. Seven was so inconsistent the character should have been controversial. The cat suit was squarely in the Star Trek tradition of miniskirts. This double standard requires a level of dishonesty that is truly remarkable.
11. Star Trek has always had some abominable stories. Thankfully, most of them could be skipped because the series was episodic. The difficulty is understanding how someone could like a serialized show whose Big Story is a disaster.
12. Another shameless double standard. Prophets, anyone?
13. Borg fatigue? There were, what? four episodes featuring the Borg Collective? Scorpion, Dark Frontier, Unimatrix Zero and Endgame? After First Contact, if there's no Borg Queen, the Borg aren't on stage. It's absurd claims like this that makes you think the real objections are not articulated.
Liking DS9 doesn't require fatuous criticism of Voyager.
