Please excuse my lack of knowledge here. Am I under to understand from your post that software that you have purchased from another supplier will check from files that you have bought from this supplier and refuse to use them based on their attestation?
If you look at the price for a Mac versus a Windows computer, I think it’s pretty obvious why people might choose a Windows device. For Linux, you really have to know where to look to buy a laptop that is shipped or warrantied with Linux. People tend to buy Windows computers because that’s what’s advertised available, familiar and in their price bracket.
Disclaimer: my main laptop is Mac. I have a secondary one running Linux and although I have a work laptop running Windows, that wasn’t my choice and I don’t have Windows on any personal devices.
