I say this as a decades-long Linux user (who has tried to evangelize it many times).
Honestly for your average home consumer, there isn't much need for a Windows PC now days.
This doesn't mean if someone gave me a manual car I wouldn't try to learn.
If your around a bunch of car people then it's much easier to over estimate how many people will want to drive stick.
Well I can agree with that, but that's not the same thing as being incapable of doing it. Both of my parents could easily install Linux, it's infantilizing to argue that they can't fill out a user wizard and select a drive to wipe.
You are vastly overestimating the percentage of the population that knows what a "drive" is. Not saying that's a good thing, but it's the reality.
In my experience most people who use a computing device may be able to tell me “this is window” or “this is Mac” by virtue of the branding being all over the stuff but for all intents and purposes these things are appliances.
In the same way most people except ambitious DIYers don’t rip apart their 500-1000 dollar washing machine to replace a worn belt the call a repair guy. Or in your case, have a buddy who knows how to do it.
