As much as I don't really have an issue with what Musk did to Twitter mainly because I don't use it, X is a shitty name. Could've made a cool new name like Phaser or XLog or something.

the worst part is that he owns x.com and is not using it.

I expect he's kind of buggered there. He likes the X name for more than just twitter so he won't want to lose control of it. At the same time twitter would be hard pressed to justify using a domain they don't control especially after the wework scandal (or a small part of it) about the same thing.

He owns 100% of twitter (indirectly), there isn't any other share holder. this can't be compared to wework.

Sure, but twitter is not financialy stable and if it goes bankrupt then it's not Musk who decides what to do with a gifted x.com; it's used in a way that makes twitter the most value for the shareholders not the majority shareholeder. And as i said (with reguard to wework) if it's not gifted and with the knowledge of the abuses that a shareholder who is lending(and by lending i mean any convoluted contract that leaves Musk in control of it) a company a key asset can inflict on a company, then it's easy for minority shareholders to sue or even agencies to step in.
