I believe once( this is an urban legend) a manufacturer in a middle income country considered going with Linux to save money and Microsoft flew out a sales rep next day to put a stop to it.
Microsoft likes it when you get a "deal" and buy a pro key for 10$. Whatever, you'll subscribe to half a dozen Microwave services ideally paying them 30$ to 40$ a month forever.
The last thing they want is you to try Linux.
However, I had the joy of watching multiple Linux desktop environments crash when I switched to my Bluetooth headphones.
Cinnamon and Budgie both crashed. No one knows why. I had to switch to Mate and then spend another 20 minutes trying to get it look ok.
No typical user wants to deal with this. They'd assume Linux doesn't work and move on.
