The only issue is that Musk vastly overpaid for Twitter, but if he plans to keep it and use it for his political ambitions, that might not matter. Also remember that while many agree that $44B was a bit much, most did still put Twitter at 10s of billions, not the $500M I think you could justify.
The firings, which was going to tank Twitter also turned out reasonably well. Turns out they didn't need all those people.
Monthly active users, fair, but it also depends on the type of users that remain. My take still is that the users X cares about are politicians, journalists and the general elite. They are still on X. It doesn't matter that some random tech worker switched to Bluesky or Mastodon, those were never profitable anyway, complained a lot and used third party apps.
