I have a lot of sympathy for this view. But the results are that a good-looking Web UI is better accepted than a consistent and full-featured Swing-based UI, in no small part because it's more difficult for Web designers to make Swing apps look good.

Primary reason it's accepted is because people generally don't have a choice. It's rare to find an alternative to any given service that offers the same functionality but doesn't follow latest designer fads.

Maybe they should bother to learn how to do it in first place?

People should do a lot of things. What they actually do is what matters. Despite all the web-inspired frameworks trying pave over real UI stacks in mobile devices, they have not succeeded in web-izing mobile UI. So, thankfully, we can turn our attention to the civil war of pubsub vs observer.

Yeah, I agree in what concerns the mobile space.

Having programmed both I genuinely believe that reacts unidirectional approach is superior to swings mvc approach.

And I even argue that it's possible to make swing apps that fit nearly seamlessly into a platform given enough attention to detail which is not a popular opinion.
