Twitter is, when it comes down to it, a website; so long as it has server farms up it will stay up. ... ... it doesn't need more than a few devs to stay running. It isn't going to break over night without software developers. He may well bankrupt the company and end up having to sell at a massive loss but even then it wouldn't necessarily stop functioning. The online reason Twitter will go offline is if Musk decides to TAKE it offline.

Think about TiBB for a much much smaller scale example; if James abandonned it tomorrow but someone continued paying the server fees, it would still be here working exactly as it does now in 5 years time. Not exactly the same with twitter but the same principle. You need devs to update and innovate, you don't need them to keep the lights on.
