(Just my personal observation)

Basically during the subreddit lockdowns most of the users there didn't and still don't give a fuck about the api changes, which is understandable. The NBA finals were going on at the time, and while that contributed towards their disdain towards shutting the sub down, I personally think even if it was off-season they still would have the same attitude. But none of that actually makes them poor users.

The issue primarily is that the whole fiasco revealed a lot of their true colors. Most of the posters are willing to bootlick and grovel as long as they get what they want; which is a place to shitpost/discuss the NBA. They do not care how trash the official app is and generally think the people complaining are crying nerds that need to touch grass. It's fair to not care about people complaining about using unofficial apps, but not understanding how the api changes eventually affects them and their precious sub is sad to see. Even worse was when some of them went out of their way to disseminate misleading information everywhere.

You know how Reddit started degrading as more and more """normal""" people started piling in? That's them basically. They never came to the site early on to grow it, only near its twilight years to inevitably cause its downfall. This place right now is awesome, but once you get a userbase that's comparable to youtube comments, it gets bad.
