Title might be a bit rage-bait-y, because it looks like spectrum squatting:

[The FCC] "threatened to revoke EchoStar licenses for radio frequency bands coveted by rival firms including SpaceX, which alleges that EchoStar is underutilizing the spectrum."

Use it or lose it is fair game with spectrum especially when your carve out is HUGE and your actual use/offerings fail to actually benefit anyone.

While yes use it or lose it, 40 total MHz at 2 GHz is reasonably narrow.

I’m actually surprised humans can coordinate well enough to manage spectrum.
