I think for every platform you could name there will be a certain sub-culture of people boycotting it for one reason or another. Sometimes it's about politics, sometimes about censorship, etc.

I do it myself too. I boycotted StackOverflow for the past 13 years, never sharing another solution with anyone because the admins on that site were hounding me about posting CORRECT answers without first checking to see if a similar answer already existed. I vowed never to help anyone on there ever again, after that. I told them, even back then, that the more correct info they collect for free, the better, because some day AI would sifting thru it, and that they were being stupid. As of 2025, I was finally proven right.

Discord is better for ephemeral style questions. Mastodon is better for sharing experimentations and explorations.
