The vast majority of people don’t know that GPS is only a one-way transaction anyways. They think most devices talk back to the satellites somehow.

To be honest, I don't think most people realize GPS is coming from satellites in the first place. Most people simply don't think about how/why at all when using things.

GPS and almost all other GNSS is indeed downlink-only. However, Starlink and other LEO internet providers could offer a two-way GNSS service if they added precision clocks in their satellites.
