- Average user

Answer for all questions: the average user doesn’t care, won’t run any of those, won’t know what fs is on their system because they will choose the default what the installer suggests. Same as they have no idea about all the ntfs or exfat details of their windows system.

I use Arch BTW. Haven’t had to fiddle with rights in the last 10 years.

What is there to learn about Linux filesystems? How is it different from a Windows filesystem, from the perspective of an average user?

Why do they care what os or search engine you use?

OP already answered, but it boils down to user friendliness for beginners.

All VPN providers I used also allow you to download a .opvn file if you just want to start a client with the config file from the CLI, but for non-techies it’s a no-go.
