This smells political, possibly retribution for crimes such as fact checking. It’s without merit. The complaint states that Facebook should have competed with Instagram and WhatsApp instead of acquiring them. But if it did so successfully, it would be likely to run afoul of antitrust law anyway.
And since when is a company under any obligation to provide its customer list to up and coming competitors? That’s ludicrous.
It’s interesting watching all the ways America tears itself apart.
