true! but the thing is: it's not just foss software. it is pretty much all software. we are all just used to the stuff that everyone uses, everyone knows how to use windows, how chrome works, how you use powerpoint etc. but we are literally just used to it so we do not even notice that it sucks. i notice this a lot for stuff like windows because i have literally never had a computer with windows and without linux on it in my whole life and do not use windows that much, and a lot of people just ask whats so bad about obvious flaws because theyre just used to it! another great example are people who do not really use PCs. they struggle with foss software, but they also struggle with the non-foss alternatives! they are not used to both!
ui/ux is shit everywhere, it is just a matter of getting used to it
I don't know how to put it into words. There's something different about the way they suck.
The best way i can put it: Foss software are made by volunteers that actually care about the software instead of some company trying to earn money. When foss software suck, it's usually because these volunteers don't have enough resources, not because the company doesn't care enough.
