True. Most people wouldn't know how to install windows. They use it because it's preinstalled and works. It's a lot of risk for the average user to attempt an install from media even if it's well guided. There's also the roadblock of having media for local backup and the migration of personal data to cloud obfuscating the access to the data even further.

It's hard enough to get professionals to rtfm.

They don’t need to know what a distro is, the same way they don’t know the difference between Windows Enterprise, Professional, LTSC, etc.

If it’s not OEM, people like us are going to be the ones installing it for them anyway.

It’s not “linux”’s job to be userfriendly, it’s up to the distro. Look at android, steam deck and chromebooks, three very userfriendly linux distros. Now we just need some billion dollar company to do what google and valve did with those for a desktop and we’re good to go.
