When I called them, they had already set it up and was playing Risk of Rain 2. They started streaming for me on the Discord Flatpak they installed from the app store.
I say this as a decades-long Linux user (who has tried to evangelize it many times).
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.
This is funny. I have an HP PC that has an option in the BIOS to "prepare for RAID" or some such. I wondered what that was, so I turned it on. I had Linux on it at the time, and nothing happened. I shrugged and just forgot about it.
Fast forward a few months later, when I gave this PC to my dad. He installed Windows on it, then started thinking the PC was somehow borked: "the installer sees the drive, installs, reboots, then it fails to boot". I was shocked, that PC worked perfectly.
Then I remembered about that setting, told him to untick the box in the BIOS, and he was off to the races.
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.
Honestly for your average home consumer, there isn't much need for a Windows PC now days.
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.
