That not an option. If Linux is a serious threat it means that a normal people could use it without any problem, with all the common software needed (Office, a browser and few other things).
At this point trying to lock down the PC to have the be able to run Windows is not really an option, people could simply choose to not use Windows anymore and be productive anyway.
Only problem are games, but it is probably solvable
Which in the precise moment when Linux is a serious threat is not possible since there is no assurance that the hardware vendors would accept, given they now have an alternative.
An it really deeply annoys me when these talented persons, who’ve spent countless hours reverse engineering crap, undocumented, proprietary technologies that the original vendor didn’t care enough for its’ users to document or open source, get blasted online by entitled brats that say “Linux sux, my AAA game don’t work!”.
While I agree with you, reading the linked article this does not seems the case. She simply said that she reached all the goal she wanted in this endeavour and then she pass to the next challenge.
Not an option, at this point a somewhat big part of the people don’t want to run windows 12 so do not care.
And vendors who agree could simply see they sells down since a, at this point large enough, percentage of the buyer prefer someone who don’t agree.
