Except for potential Anti-trust litigation, I don't see any reason for Apple to 'not lock' its M series computers from boot loader to app store in the near future as the walled garden + vertical integration has been their most successful business strategy. One should be naive to think that the conversion to M-series wasn't done with the intention to lock the macOS platform akin to iOS. I wouldn't be even surprised if doing so didn't attract anti-trust issues as they got away with iPhone, iPad which are not lesser computer than a PC especially since several applications are becoming 'mobile first' or even 'mobile only'; So it's ridiculous to compare smartphones, tablets to game consoles whenever this topic is brought to the discussion.
