Why do you think it is going to be more private than 3G? SpaceX can observe your connections, Starlink is hard to pay with cash, it still needs a precise info about your location.
I don't have an answer. I feel stupid for it. I thought I had all the answers but I didn't think this through. I thought getting rid of cell tower triangulation you can achieve privacy but you'd still need to connect to a satellite with a unique network identifier.
ok, so spacex knows where you are, who you are, etc, but not what you are doing. traffic is fully encrypted, so they dont know if its a phone call, text message or web page your hitting... add in Tor or something like that and things are a little more private... yes, the knowing where you are and who you are is iffy, but at least the end data is encrypted...
