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
Disagree strong. Every turn and chance, revenue is given preference over ease of use. Cookies, tracking, free trials where you need to either log in or add your credit card are trends that are very annoying for users. And from there we can get into specifics of what the app does.
It also doesn’t explain why every software made in Microsoft, either from scratch or bought after being successful, is the absolute lesson in UI anti patterns.
So OP edited his post to be about being ‘user-centric’ and not ‘user friendly.’ There’s a huge difference between being easy to use, even for the technologically illiterate, and being good for users so I wouldn’t disagree with a lot of what’s been said in this thread
