PC OEMs could totally ship their machines with linux installed, or even with multiple distros to choose from at first boot. And one of those options could even be Windows 11, the user would just need to enter a key or buy a license after booting up.

It's just a question of motivation. Do they think their customers want it, and do they expect Microsoft to make their life more difficult if they try?

Honestly now with so much of the civilized world looking to break dependency on US tech, I hope that Europe sees a big push towards mainstream off the shelf linux devices.
