I'm not worried about Twitter because it's mostly nazis and bots over there. People of good will are leaving. I'm really nervous about Meta. If they manage to make a more tool-rich interface, friendlier to users, it might suck a lot of traffic over. And they can always enshittify it, monetize their version of ActivityPub, or scrape and monetize Masto users, after.
The referenced tweet:

(Just kidding, I didn't try. Screw that guy. I tried on a different link, and it gave the attached message.)
"Twitter lose a lot of user, data are very bad -> try to increase user with a very stupid idea"
In 3 days, Blues user will moan because nobody reads them
