Reddit (the company) deciding what communities can be about is actually not new and I wish it were widely known. The first big example I know of goes back to 2018 when the admins overrode a subreddit creator to force their community to be for (pro) gamergate content.
I honestly get it to some degree. ~50% of threadiverse users are people banned from most of reddit and are the most hopelessly miserable and arrogant assholes to be around. On top of that, the main content feeds are overwhelmed with low effort memes that give the whole Threadiverse dead-internet vibes. Until the larger instances actually take steps to make themselves welcoming while creating space for real discussions I wouldn’t blame anyone checking out lemmy.world (or whatever) and just noping right back out like the grandpa Simpson meme.
