If you see popular, simple-to-use, proprietary tech and conclude "people are idiots", you are fundamentally out of touch with what people want/need. Should there be straightforward FOSS tech? Yes. Is there? Not as far as I know. Installing Linux Mint took me a day and involved a significant amount of time googling problems & using the terminal. In comparison, starting up my brother's MacBook took 5 minutes. Most people have shit to do, and will pick an option that doesn't get in the way of that.
