Literally this. Any examples of what exactly has changed?
Same goes for NSFW stuff, that stuff has been on Twitter long before Musk bought it and it will still be available just marked as sensitive (like it always has). I doubt they will go the Tumblr route and kill a giant part of the userbase.
It's not cool anymore to be in it. In fact it's cool to your aspirational peers to say you dislike it now.
