Microsoft doing that would be wild.

You used to be able to put it on Macs yourself, i.e. just install it the way you would on any computer, or equivalently put Linux on it. Now, see (all the work that has to be done by the team of) Asahi, except there's no Windows equivalent.

If MS did 'Asahi-Windows'... I don't know whether I'd expect Apple to sue or to make ads making fun of it, but it would be a wild time.
