I would claim that many people would be fine using something else because they use 30% of the features of the respective applications.
They end up using Windows (or Android, or iOS) also because because that is the only option when you go in a shop to buy the hardware. I have a hard time buying a computer without Windows installed even if I actively want to!
As the netbooks wave has proven, followed by Android and ChromeOS one, is that when you go to the shop, you will be getting a laptop with Asus Linux, Dell Linux, HP Linux, naturally branded with cool names from their marketing department, and full of usefull apps as differentiation factor, and naturally the related Linux drivers are only available from their respective support pages for the usual support timeframe.
They might eventually add support to something like Ubuntu, alongside their own OEM specific distribution, but naturally folks will complain they cannot install NixOS, and eventually they will remove those devices from the shops, as their sales become a rounding error.
However I do agree BSD and Linux distributions seem to be the only way to get independence from USA powered OSes, especially if we get back into the export regulations with the current ways of the administration in power.
