My own pet theory, based on absolutely no inside knowledge, is that MS doesn’t want to have Windows on M1+ until other CPU makers have caught up to Apple. It would be a huge embarrassment to have Apple hardware running Windows that much better than all the native PCs. All the PC OEMs would slash Nadella’s tires.
I like the theory, but I’ll counter with my own theory that MacBook Pros were the best Windows laptop for many years, and they ended up pushing PC quality to catch up which was good for the Windows install base and Office. :)
