I think the main ask should not be limited to android/ios but similarly to the rules and regs of previous decades around agressive interop and standardisation. Asks for piecemeal carveouts whenever a monopoliist tightens the noose allows the can to be kicked downn the road when the outrage has subsided and allows for entrenchment of the status quo by stealth. Chipping away until the stated goal is reached. Just like the car/gas monopolies were not alowed to get away with locking users into their own cartels - similar efforts should (but probably wont) be taken to preserve the ability of users to do with their devices as they see fit.
