Let’s say just like for example like MacOS. It’s awesome we have so many tools but at the same time lack of some kind of standardization can seem like nothing works and you get overwhelmed. I’m asking for people that want to support Linux or not so tech-savy people.
ChromeOS does this well because it’s android, a walled garden that users aren’t allowed to break. You can buy it at Walmart, and it works well.
Other big “consumer” distro projects (Debian, Ubuntu, fedora, rhel, etc) are similar, especially if you’re installing stable releases on hardware that is supported.
The question for me is what do users want their OS to do? My guess is internet, office, print, scan, photos, games, updates, and get out of the way. Almost all big distros will give you that experience already, as long as you don’t expect to play Windows games or pick a specialized gaming distro.
Users who want to step outside using supported repos are back to googling for a solution when things are broken, and should see themselves as part of the tech-savvy group that need to fend for themselves.
