As the article says, Apple is changing iOS in the EU to prevent non-Safari browsers from adding PWA icon links to the home screen, making this feature exclusive to Safari (and granting Safari an anticompetitive advantage). Apple did not remove PWAs in Safari, but they removed the ability for PWAs to be displayed full-screen in Safari in the EU.
Nothing in the article says that new PWA links can't be created in Safari. Read carefully:
> PWAs can’t be linked to alternative browsers.
If the situation that you think is happening were true, the article would simply say that Apple removed PWA links from iOS, instead of specifically saying that the removal applies to alternative (non-Safari) browsers on iOS.
