Re: Iridium?
Iridium is more than still up there, they launched a new constellation recently. They are going to be pushed further into their niches, because their data offering will be swamped by Starlink and all the other upcoming systems.
But those niches are really quite important eg the Pacific Ocean tsunami warning system relies on one of Iridium's very unique services which no one else is replicating. There might come an awkward point where they need to continue being funded for the sake of those niches, and the US DoD gets to pay for it (a bit like they run GPS and let us use it for free).
