Musk has banned Twitter users from posting information about where to find them on other sites.

Of course, you shouldn't be used by Facebook or Instagram at all, anyway.

Twitter's policy may be illegal in the US. I wonder, though, whether FTC enforcement power can prevail against a billionaire who is willing to lose millions of dollars as a result of his choice of policies. If he chooses to defy the FTC, can they do more than fine Twitter a few million?
