He's right. Apple has been strangling web app progress on iOS for many years. They wanted to ensure that web apps could never compete with native apps on the App Store, because they can extract their 30% fee. Now that Apple are forced to permit third party browser engines, web apps would suddenly be a lot more powerful. Apple just won't have that, so they're disabling a useful feature for everyone. I think this will…
As much as I would love to agree, the general population really does not care about features like "home screen web apps". Nobody outside of HN even knows what they are. Everyone just goes on the app store and downloads random website app. Even if it is just a browser app that renders a website. Apple would have to eliminate something that people actually care about for any boycott Apple to happen.
They could do the same for web apps. What's been limiting them all this time is Apple policy.
Apple policy 1- PWAs on iPhone must use Safari, Safari only has features Apple chooses to implement
Apple policy 2- Add to Home Screen is hidden away
Now with DMA, Google could make its own web browser, provide all their apps as "PWAs that work with Chrome and not Safari" and people could go along with it. Heck they could even start their own app store without the apps having to follow any of Apple's "alternative distribution" rules- because they're web apps, not native apps.
