Eldenroot You misunderstood me, that's already stated in the license section both in the README and in the post here, what I meant is that in previous versions the user was also responsible for purchasing a license when their site went from being non-commercial to commercial, it's not something that I as the maintainer of the extension can take responsibility for, nor can I control beyond indicating it.
For that very reason the official packages are released without any restrictions and the users have the ethical responsibility to follow the license guidelines.
As also specified the Fancybox UI components (v4) can be used for free during the development or staging of your project, after that you must purchase a license, I don't think there is anything tricky about it, it's quite clear.
