I mean in some ways twitter did die ages ago in that its user base has stagnated over the years and its relevance has dropped outside of a certain powerful minority of users.
The "powerful" users (like Musk) are it's relevance. Tweets are quoted more than ever as the primary source of information when they are know to be "official" accounts, or owned by a specific person of interest.
Embedded Tweets on a news website might not be a great way to get ad-views, but those accounts give it relevance beyond the users who actually interact by commenting.
I expect Matt Levine’s take will amount to some version of this; Elon Musk uses Twitter to make a lot of money via his various market manipulations, one risk to that is Twitter doing something to make those market manipulations harder, so a way of mitigating those risks is to buy as much of Twitter as possible to get as much of a say as possible, in an effort to prevent that from happening.
Surely Elon has made $3bn off of Tweets by now, it makes perfect sense for him to spend some of that as a way of protecting future additional earnings, both for him and the various companies he runs that also make money off of Elon’s tweets.
