The GNOME desktop environment - https://www.usenix.org/legacy/publications/library/proceedin...
"Sadly, the KDE effort is based on the Qt user interface toolkit which is a non-free library. The main problem is that modification of the toolkit is not allowed. The ability to modify the interface toolkit is a requirement of free software[6] and of the Open Source Software Guidelines[17]. Although Qt is released in source form, permission to redistribute changes made to it is denied."
Indeed, there even was an attempt to produce an open source clone of Qt for KDE when Gnome was still getting started: https://en.wikipedia.org/wiki/Harmony_(toolkit)
This is wrong. GNOME was already well underway when Qt switched to GPL. Before that it used QPL and before that yet another license.
