You do realize that X is now it’s official name right? Elon changed the name to X and deprecated the twitter name. At the end of the domain registration, he is not going to re-register twitter.com as the domain name, and because he owns the trademark on it, he is going to sue anyone who tries to re-use the domain name.
Nothing wrong with that. When I see a re-post from X/twitter, or whatever he wants to name it in the future, I happily scroll right by it.
I say let him go bankrupt trying to save it.
