He hasn't said, but I suspect a couple reasons limitations on what SpaceX can do, orbital changes, protocol changes, etc could all affect people depending on something that Starlink wasn't intending to offer in the first place liability, what happens when the navigation gives the wrong location because of a change Starlink made. to use the satellite signals, you not only need the timing, you need rather precise orbital information. If the satellites are modifying their orbits autonomously, how does that information get to everyone? For normal Starlink purposes, the satellites determine which sat is covering what area on the ground and the ground stations can react to the different sats that they hear (beaming back on reciprical bearings or the beam info can be in the handshake) but navigation requires getting the signals from many sats at once to work out the timing between them note, I have no inside info, this is just my version of logical guessing.
