There are at least 2 other serious players in LEO satellite constellations who have launched prototypes or will shortly. Oneweb (which doesn't do sat-to-sat comms, so is just a "last mile" provider, like Globalstar is for sat phone) and Telesat (following an Iridium-like sat-to-sat approach, just like SpaceX is), which launched a bunch of prototypes even earlier than SpaceX did. ...and a whole bunch of other players. So competition is definitely a thing.
