Not OP, but my experience with Linux is that seemingly absurd usability issues just keep piling up the more you use it and at some you just kind of give up and abandon any expectation of even a decent level of common sense from whoever is developing the system. I've listed some of which I encountered on Mint here https://www.virtualcuriosities.com/folders/273/usability-iss... Among them: AppImages just don't run unle…
Not to argue with you, but is that Linux Mint specifically? I never used it, and its DE looked very unprofessional to my liking. Personally, I prefer modern Gnome, but I also like KDE. Everything else looks very unfriendly to an average user, I won’t ever install it. I’d go Gnome for Mac users and KDE for Windows refugees.
The fragmentation of Linux leads to a ping-pong of responsibilities. Linux can never be a bad OS because it isn't an OS.
On Windows, if the file manager is bad, that's Microsoft's fault. Period. Nobody tries to say "actually..." it's Microsoft's fault. Period. The same goes for the taskbar, for the control panel, for MS Paint, for even Microsoft Office. If Microsoft will fix it or make it worse depends on them, but nobody denies who is to blame and everyone know where the blame lies. Meanwhile I don't even know if the basic utilities that my distro distributes are under the responsibility of Mint's team or if they will just direct me to some random open source project's issue tracker if I start complaining about Celluloid or the "Drawing" app.
You can't talk about Linux thinking only about the good parts, or you aren't inviting people to try Linux, you're inviting them to try your distro. "Linux" means the whole ecosystem, including all of its problems.
