RDP works great on Linux as well. The problem isn't remote access, it is lack of good cross platform GUIs. There is a reason browsers are dominating the UI space and TUIs are popular.

Qt is still around. And there's stuff like Avalonia.

The problem is that people don't use that and reach for Electron instead, and then you get that "bad on any platform (but good enough to ship)" effect.

Yeah, laziness, we had plenty or cross platform GUIs in the 1990's.
