All the Apple ecosystem developers left, all the neo-Nazis were unbanned to add subscriber numbers, I see 1-2 ads a day because all the respectable advertisers left due to the Nazis[0], and the For You page now regularly does things like show you tweets from locked accounts, circles you're not in, and people who've blocked you.

Elon seems to have given up; he's just doing jokes now like changing his name to Harry Ballz and replying to fake news from the fake news accounts he unbanned.
