One of the few actually beneficial parts about a centralized, corporate entity like twitter is that even if Elon fucking eats it, the place can and likely will keep churning.
Someone will inherit it, it'll get auctioned off, something. It won't just fucking disappear.

Of course, it comes with many drawbacks, but its bus number is absurdly high. A LOT of people gotta just be snuffed out for twitter to suddenly die and stay dead.
