Musk has always been pretty transparent that that was his ambition for X.
Musk has said over and over he doesn't care about advertising revenue, he mangled a quote from the Princess Bride to say "I don't care" and then he said if advertisers try to blackmail him with money (even stranger phrasing) they could go f*ck themselves.

I think gaining the influence to fire regulators investigating his companies was what he wanted.
BTW he sold Twitter to another subsidiary of X Corp, I wonder if he paid back the debt from the LBO of Twitter.
I don't think they care about the experience or functionality. I think it's just about being able to exert enough of a legal or structural claim to get their fingers on a cut of the eventual transactions enabled by the various "apps" in the "super app".
