Oh hmm, I'm honestly not super sure then. I know Gluon is the one that's seemingly has a business providing JavaFX support, while Oracle.. as far as I know doesn't offer a license or anything services in that direction? But I could be wrong. Gluon is mentioned in the article.. they have a very Qt-style confusing licensing situation where it's probably all free.. but you're never quite sure :)

The whole space is a lot more icky than one would like it to be.. Which is unfortunate b/c while it doesn't have a billion features, it's a nice composable reactive framework to use (at least from cljfx/clojure)
