Don’t get me wrong. I love Linux and FOSS. I have been using and installing distros on my own since I was 12. Now that I’m working in tech-related positions, after the Reddit migration happened, etc. I recovered my interest in all the Linux environment. I use Ubuntu as my main operating system in my Desktop, but I always end up feeling very limited. There’s always software I can’t use properly (and not just Windows stuff), some stuff badly configured with weird error messages… last time I was not able to even use the apt command. Sometimes I lack time and energy for troubleshooting and sometimes I just fail at it.
I usually end up in need of redoing a fresh install until it breaks up again. Maybe Linux is not good for beginners working full time? Maybe we should do something like that Cisco course that teaches you the basic commands?
For most people computers are just the same as cars. People want a car that will drive them from place to place, are easy to refuel, easy to operate, and can be taken to an expert for anything difficult or that requires specialized knowledge. Same for computers. Most people want a computer to navigate the web, install the apps they are used to and that their friends use, is easy to operate, and can be taken to an expert for any involved work.
Even the friendliest of Linux distro don't check all those boxes. You cant get ready support from a repair shop, many of the apps are different or function differently, and it doesn't receive all the same love and attention from major third party developers as Windows does.
Most people could learn to use Linux; it's not that hard. Most people could learn to change their own oil. But for most people, it's not worth it. For most people it's not the journey, it's the destination and cars and computers are just tools to get there.
To use your car analogy, using Windows is like using a car that has the hood welded shut and can only be opened with a special key that only the auto manufacturer has.
You can’t repair it yourself. You can’t just take it to any expert to get it fixed. Only the manufacturer can fix it, because the source code (or car hood) is closed.
