> Let’s face it, most quality Linux desktop apps use GTK.

As I wrote above, more than a few large applications have switched away from GTK to Qt including Wireshark, Openshot, and now Audacity. How many large apps have switched the other way?

Then there are the "quality" apps that have always been on the Qt / KDE side of the fence: Kdenlive, FreeCAD, Krita, Scribus, qBittorrent, Qt Creator, Dolphin... And that's free software. It is a slam dunk for Qt on the commercial side.
