Uncertain what Iridium global RF band allocation holdings were worth.

If it is still pole-to-pole global monolithic coverage, than hardware/legacy-protocols are of secondary interest. Modern SDR transceivers with proper RF beam-steering front-ends could retrofit the business while slowly phasing out legacy hardware.

But I do agree, Iridium was too pricey for most consumer product markets, and there were several other satellite broadband services.

Additionally, Starlink Direct to Cell (VoLTE) service now leverages global cellphone client infrastructure. It would be extremely foolish to compete with something proprietary. =3
