@altavir I'm a bit late, but I can point that JavaFX has a lot of issues with media and browsing capabilities. Not to mention memory consumption, though it can be tackled with proper GC settings.
Qt has much wider community and there are more libraries to extend the framework. The number is much lower than WPF, but still big enough. JavaFX, well, I think there are more jobs for Swing/SWTF than JavaFX.
Also there are PyQt bindings. People tend to prefer Python because it has simple learning curve. It's much faster for to use PyQt than any statically typed language for entry-level developers.
About the news: I think if Qt company won't change policy, it'll be forked eventually. It seems they do not really care because of all the contracts from automotive and proprietary desktop programs (like any big 3D software).
