“Just install Linux on it” is the “just change the engine of your car” of tech.
Not everyone is a mechanic, not everyone wants to be a mechanic, and, if we want a world where freedom is the norm, we must stop expecting everyone to become a mechanic.
Note: this is not because these people are too dumb to be mechanics. It’s because they’re brain surgeons and space-shuttle pilots and they have three kids and they care for a loved one and they don’t have time to also be a mechanic.
@aral Unfortunately, in order to compete with the status quo, you'll first need to create some awareness and demand. Right now, PCs with preinstalled Linux are either Chromebooks (pretty infested) or cost significantly more than regular old laptops. They need to move from the "artisanal organic" price category to a point where you don't pay extra and "I heard somewhere these are good" is enough to get someone over the threshold.
