It kind of died, twitter as it was even though X is still running and somewhat recovered in terms of infra.

Musk effectively left his newest plaything a few months after the takeover and some events like him going in in a datacenter and disconnecting servers, that was when Twitter (I'll call it X when he acknowledges his daughter) started to stabilize again.

All that he seems to be doing these days at Twitter is messing around with the recommendation algorithm, override the decisions of what's left of moderation for his far-right friends and that's it. Oh and of course Grok/xAI or however it's called these days, but IIRC that's a separate corporate entity that just got shoehorned onto Twitter.
