Also the point about using Docker for GUI apps is crazy. I've never seen the need for such thing. AppImages, Flatpaks, heck even Snaps exist and allow developers to distribute applications along with the dependencies. They have their issues but they're good if the developer does not have much time to mess around with deps and testing in different distros, some users also prefer them due to "sandboxing". I'm not saying Linux desktop is perfect by any stretch of the imagination, but it's not the clusterfuck NavinF is talking about.
