So what about FB replicating all of SNAP and overtaking them rapidly, taking the advertising growth market share they would of had otherwise? Time to breakup FB?
That just means SNAP sucked if it was that easy for Facebook to entice users. They in no way forced people to use their SNAP replica or charged less than SNAP did.
Is Snap actually in a separate market for antitrust purposes? Looks like the same market to me, but of course that decision is always a somewhat arbitrary judgment call made by the antitrust enforcers and court system.
