The last I heard, Linux is not coming to M1 unless Apple opens up on technical specifications.
But thinking about it, it might be that the mobile AMD CPUs are a year behind the desktop ones. So next year the best ryzen could still be at 7nm Zen3. In that case apple will have a 2 year transistor lead. But, will see.
Of course, next year laptop models are probably being finished right now, and it could be that intel still found a way to bribe premium manufactures from including AMD in their premium models.
In my opinion they'll lose marketshare if that happens. But, there are most likely smart people with a lot of more information than me making these decisions.
That won't satisfy the purists, but it should satisfy the practical in most cases.
