I'd say there's plenty of room for competitors along multiple dimensions: Geopolitical security (this alone will probably preclude a single monopoly), price and lack of a moat (once a monopolist starts jacking up prices, there's an immediate incentive for an alternative), delivery profile (store-and-forward for IoT-like use cases vs. dumb pipe vs. in-space forwarding), frequency band (L- or S-band for direct to device vs. Ku/Ka band requiring directional terminals) etc.

The only thing that's actually scarce and that could be monopolized rather easily is frequency spectrum. In fact, I suspect this to be a frequency/operating license driven acquisition.
