QT C++ Desktop End of Life?

which widgets were removed from "free" usage in Qt6 but were available in Qt5?

I don't think anything was removed between Qt5 and Qt6, at least not in the QtCore, QtGui, and QtWidgets components. There could have been new things added in Qt6, but since I'm not using it I can't tell you what those might be, if anything.

As the OP said, there have been many additions to QtQuick/QML which apparently do not have corresponding implementations on the QtWidgets side. In the early days of QtQuick and QML, things implemented on that side were also implemented on the QtWidgets side, but possibly that is because most of the work was in ensuring that QtQuick and QML were a more or less complete mapping from QtWidgets and not the other way around.

What licensing changes are you referring to from qt5 to qt6? I was under the impression nothing much changed. Dont see anything in https://doc.qt.io/qt-6/license-changes.html either.

I was using Qt5 under a commercial license. For Qt6, the terms were changed to a model where you had to pay for the license every year for as long as your product was available for sale, even after development had stopped. I did not want to be held hostage to that kind of license. The Qt5 commercial license is perpetual and I don't have to continue paying if I don't want support. The Qt6 license is also very expensive, too much for a 2-person software company, only one of whom uses Qt.
