I would argue it was always like that. Some of it seemed to be actively encouraged by Jeff Atwood/moderators/senior users. You forgot another common one: "not clear what you are asking". I normally have to reply to this with "the question is in the final paragraph". Which often results negative comments and perhaps the question being closed. Or trying to edit a bug out of an answer, being refused because you didn't change enough, tidying up some wording, and getting the edit rejected for supposedly changing what the person is saying. I don't think any of it is specific to SO - online communities seem to attract people who like everything to be extremely specific and rule-based, regardless of whether that creates the best outcomes. I've seen mods destroy several forums. SO gets a lot of other stuff right though. I don't think it will die anytime soon, nor does it need to in order to improve things.
