It's a shame, really, that QT didn't have a GNU loved license more early. In a better timeline, we could have skipped GTK, Gnome, and have a unified desktop UI. Right now, Gnome is the darling of Red Hat and GNU, and we all lost for it.
This is where the multiverse would be interesting. It is not Movies like Marvel... it is to see a universe with the above. Would QT be as good as we think?
