Yeah but with the volume we're talking about here, SpaceX is definitely going to be extremely constrained by launch capacity. I doubt they'd be hit with any antitrust lawsuit over not cancelling their own launches in order to take orders from their competitors. In any case, there's no chance that all of those companies are going to be able to launch their constellations in anywhere close to their targeted timeframes. There's just not enough launch capacity in the world to handle that in such a short amount of time.
