I think Elon knows that twitter is captured by elite special interests (cough SA cough), and they are not interested in price, only influence on the global overton window.
He is exposing this to the shareholders, who majorly probably know this already, but he's also giving them an opportunity to seize twitter and turn it into an cash cow.
I believe if Elon takes twitter private, their valuation will double overnight. The only reason twitter loses market share is because of censorship and lack of innovation. Elon as CEO could flick a switch and both those problems would be gone.
He may also be secretly working with Dorsey, who has been working on a decentralized version of twitter for a while (project Bluesky). But it's really hard to get people to switch to a new social media platform.
