I have no idea why it wasn't more obvious to me that Facebook would do this. It's so obvious now that it is happening.
They have attacked every social network format to date. They'll probably take down Reddit using ActivityPub afterwards, but for now, Twitter is the easiest target.
Meanwhile I read the feed and get stressed by people (un)consciously installing Threads cr-app on their primary devices w/ stock Android and iOS, despite them having a normal time with literally any other interface to Fediverse.
They have plan to adopt the same standard "in future". That mean we have plenty of time to check the beast from afar. Not perfect but not an immediate "thread" either.
The problem right now is that ask a s***load of personal information to use the app and if later you want to leave, you can't unless you erase your Instagram account too.
I think much like Lemmy you just want to find one that fits with your ideals. Check the rules and whatnot and make sure you are willing to comply with them.
I wouldn't call this a recommendation but personally I went with Fosstodon.
I didn't really look very hard before selecting one of the first few I came across though.
