And yet Linux and to lesser extent Windows and even lesser macos exist. They don't have that excessive control and we still can use bank/financial goverment and (if we enable DRM) also copyrighted media webpages (and sometimes apps). Aside from music/video there are no obstacles for other apps to exist in open system.
