Any software license you may have purchased is a non-exclusive one. Apple can re-license their own software however they wish.

That’s not true though. Users can already sign and sideload apps from a Mac. It’s just that doing so imposes annoyances (have to manually update apps, and resign every week). Allowing proper sideloading would only eliminate annoyances associated with current capabilities.
