Is it irritating to read multi-page comics as one long strip?
For me, it's great this way. As long as it is a direct image link. That way my browser does the scaling and I can easy zoom in. Some sites (like imgur) prevent you from direcltly opening the image, prevent zooming and even downscale the image to a blurry mess.
They will try. This is about OS-level APIs. In order for a browser to to install and run PWAs, it needs certain OS APIs for e.g. home screen installation, storage and notifications. iOS currently has these APIs but Safari severely limits what you can do with it. Now the DMA will force Apple to accept other browsers, which have no such limitations. So, Apple now wants to remove these APIs altogether and kill PWA support outright, before that portion of the DMA takes effect.
There probably will be a lawsuit and Apple will probably lose, but it will take years to resolve that. And in the mean time PWAs remain dead and the only way on the iOS home screen in paying the 30% app store cut.
