I think Musk's satellites have a satellite-to-satellite link in a mesh topology with each other to have true redundancy. This is something that Hughes and Viasat probably did not put any major investment into doing with their satellites due to not owning enough of their own satellites or leasing other satellites and transponders. The intersatellite linking Starlinks satellites have also means there does not have to be a significant number of earth uplink stations connected into the fiber optic networks of other countries.

That's pretty nifty. I bet the latencies are shit. But up there it should easily work, with line of sight and zero interference.
