Twitter is heavily in debt. It's losing more money to interest than it has been earning, even before Elon shat on advertisers.

I don't expect Twitter to go bankrupt, but it will need desperate measures to stay afloat. When it'll come to "either we do this or we go bust", they won't stop at anything. It's likely going to be a massive sell-off of user privacy on a scale that will make people run to Facebook for safety.
