Don't be fooled. People like Elon aren't pro-free speech. They only want their speech. For example on Elon's X you can call people all kinds of things but calling someone "CIS gendered" is a ban-able offense [1]. Linking to other platforms was also forbidden for a while and in the H1B discussion X shadow banned a bunch of people [2] and I could go on for a while.
Do as I say, not as I do.
