And then there is the little detail that this is being decided for the whole world but actually just benefits one, possibly two companies from the United States. Space belongs to all of us, not just to the USA.
How come I can't easily find a registry of the UP/DL/Beacon transmission frequencies for every satellite. Am I just not looking in the right place? I can find various hobbyist's catalogs, but nothing that looks remotely official. Any satellite with downlinks between 30 MHz and 1.2 GHz is potentially useful for helping to calibrate one or more of the radio neutrino experiments I work on.
A good source of downlink information is the FCC International Bureau records of satellite ground stations in the US.
Also note that this shows licences, not actual use. You can have a satellite licenced to a particular frequency but not using it.
