Free software scares normal people

The open source UIs initially seem alien, complicated or obscure related to similar to closed-source Windows' ones. The reason is OSS projects are built by developers primarily FOR developers and not for regular users. The design principle of "Don't surprise me" and other artistic and ergonomic ones are not met. Examples are Gimp and other content editors like Handbrake, Firefox vs chrome in mobile only, even IDEs.

BUT with time and a variable effort a regular user can get accustomed to the new philosophy and be successful. Either by persistant use, by using different OSS apps in series or by touching the command line. Happy user of Firefox, Libre office, Avidemux, Virt-manager (sic)

Is Firefox v chrome even relevant these days? I struggle to even think of shortcuts that aren't identical among the two browsers. Let alone UX and features.

I think the other big reason is availability of talent. FOSS is made by devs who usually are already well off and have time to contribute. You wont find as many artists nor graphic designers with the same privilege . so if there's bo designers on a project you get the bare basics.
