From my experience, most FOSS software is very user friendly user-centric / user-focused, while proprietary stuff is shit. What is the most notable exception to this rule that comes to your mind?
Edit: With user friendliness, I don’t mean UI design, but things like how the software is handling user privacy, whether it sees its users as users or as money-making cattle, how it handles user feedback, compatibility with other software the user uses (vs. vendor lock-in), configurability, and similar issues.
Edit2: I was made aware that user friendliness is a defined term: https://en.wikipedia.org/w/index.php?title=Userfriendliness
I also use arch, btw, so yes I’m probably biased in a similar way as you.
Most FOSS software I downloaded is very friendly to me, thanks. Or do you have a particular unfriendly FOSS software in mind?
Btw, out of interest, if the software you use is so unfriendly to you, why do you use it? Money reasons?
Have you tried Calibre?
