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.
Twitter/X is the reason DJT became President. It happened accidentally (ie against the wishes of Twitter management) in 2016, they successfully suppressed him in 2020, and then Elon gave MAGA that platform in 2024, leading to DJT's successful election.
As long as X is seen a kingmaker, someone will find it profitable to own/maintain, even if it doesn't convert Ads like Meta/Google.
I really don't think so, at least not in isolation. It probably contributed a small part but the right wing media machine is multi-faceted. There were a lot of podcasters (i.e. Joe Rogan), comedians and youtubers all publicly in support of a second DJT presidency and I think that had a much bigger factor overall than Twitter.
