A lot of stories like this have been coming out, but it's not clear that they foretell the doom of Twitter as so many people are assuming (or anticipating).

Donald Trump's various businesses showed long ago that large companies aren't necessarily harmed by shitty practices like not paying bills. And mid-2010s Reddit showed that a social media platform, once established, can survive terrible technical deficiencies (remember when Reddit was crashing daily?), simply because people tend to be too lazy to move.

Most likely outcome is that Twitter continues to chug along, maybe with outages here and there, not losing much traction. Maybe it ekes out a small profit, which Musk can use to salve his ego.
