Which - in my considered opinion - makes them so much worse.
Is it because writing native UI on all current systems I’m aware of is still worse than in the times of NeXTStep with Interface Builder, Objective C, and their class libraries?
And/or is it because it allows (perceived) lower-cost “web developers” to be tasked with “native” client UI?
I found it kinda weird that the page this link opens on makes it look kinda like a closed source freemium thing, and (on mobile) I had to dig a fair bit to see that it’s actually FOSS and an official part of the KDE project.
I run KDE as my daily driver, and hadn’t heard of Krita before; so yeah, I guess it could use a bit more exposure.
