> I'm curious - why is facebook required to promote a competing social network?
They aren't required to promote, but arguably also can't actively find ways to prevent it from trending "organically" as that could ostensibly constitute an anti-competitive practice
- actively discouraged IG users from discussing Snap
- prevented Snap from trending on FB
- used data from an acquisition Onavo to track what users did on other apps (such as Snap)
Furthermore - whether or not these shady practices were the downfall of Snap does not absolve FB from doing them.
