Perhaps we should stop viewing iOS/Android devices as true general-purpose computing devices. They are merely gadgets, like Walkmans, portable CD players, game consoles, blood pressure meters, car infotainment systems, etc. They contain CPUs with enough power and RAM to act as general-purpose computers, but Apple and Google did not design them for that purpose. However, Windows and macOS were designed as operating systems for general-purpose personal computers, and restrictions on the software you can run are also happening there. To me, this is more worrisome than the openness of mobile OSs.
