Most users have not abandoned Twitter as it collapses. Mastodon gets mentioned much less than it did a few months ago, and while an invitation to Bluesky, backed by Twitter founder Jack Dorsey, was the hot ticket six weeks ago, most people seem to have shut up about it again by now. Twitter is still the best approximation of Twitter.

So to sum up his point, Twitter alternatives are failing because no one on twitter is talking about them. But takes like these are fundamentally missing the point, the people who pushed for those platforms have left for those platforms. They're not adding to the conversation on twitter anymore (why would they?) so what the author is seeing is an increasingly worse and worse circlejerk. Unreasonable and incorrect opinions become louder and more visible, gradually pushing reasonable people away as they each reach their individual tolerance levels for bullshit. You can watch it in real time right now on reddit, posts are getting more and more critical of the blackout protests. This is the true way a social media platform dies, mass sudden migrations are the exception, not the rule.
