Thinking they didn't keep up with the times or that they should've made changes is perfectly fine. It's the vitriol in some of the comments here I really can't stand.
As for me, I also don't answer much anymore. But not sure if it's due to the community or frankly because most low hanging fruits are gone. Still sometimes visit, though. Even for thing's an LLM can answer, because finding it on SO takes me 2 seconds but waiting for the LLM to write a novella about the wrong thing often takes longer.
Doesn't help with how often it is wrong, but if you preface every question with "terse answer please" at least you don't get the superfluous text tsunami and it sticks to the point.
I found myself contributing less and less (same with Wikipedia), because I merely wanted to continue honing my craft through learning and contributing technical data with others who shared this same passion... I did not want to have politics shoved in my face, or have every post of mine have to be filtered through an increasingly extreme ideology which had nothing to do with the technical nature of the site. When I had my SO suspended with no warning or recourse for writing "master" in a reply, I knew it was time to leave for good. Most of the admins on the site transformed from technical (yet sometimes brash!) geeks, into political flag-waving and ideology-pushing avatars (including pushing their sexual agendas front and center), and not of the FSF/FLOSS kind, either.
These types of dramas have infected nearly everything online, especially since 2020. Even Linus has lost his mind with pushing politics into what should be purely technical areas https://news.ycombinator.com/item?id=41936049
LLMs were a final blow for many reasons, though I think that a huge part of it is that LLMs won't chide you and suspend/ban you for wanting to stick to strictly technical matters. I don't have to pledge allegiance to a particular ideology and pass a purity test before asking technical questions to an LLM.
This really sounds like people were letting their personal flags fly (in avatars or sigs or whatever) and you could not stand to see that because they were not like you. All you have to do is ignore it and look at the content.
This reminds me of someone I worked with, who asked me "why does [Colleague 2] have to shove his gay lifestyle in everyone's face?" after that Colleague 2 put a framed holiday photo with his husband on his desk.
The person who asked this had a photo with his wife on his desk. He was unable to understand (A) how that is "shoving" his sexual orientation in other people's faces to the exact same degree as Colleague 2's photo was; and (B) that the photo was for Colleague 2's own comfort and solace, and for positive engagement with anyone who wanted to engage in same, and that nobody else was required to dwell on it or give it a second glance.
