back in the 90's, 99% of people didn't want linux either, and MS did just fine without "physically" locking you out of their competition.
So either you want something that already exists or you want something new, and I'm very confused as to your initial post.
at least according to this [1] article, MS requires secure boot in win 10. and the criticisms about UEFI and how it makes linux much more difficult to install (which I have experienced firsthand) are documented on wikipedia [2]. I'm going to enjoy my friday evening and not try to make a solid case, but of course microsoft denies that they ever intended to use UEFI to block competition (because they've never done that before :) ).
