The title appears to be quite the reach. If Apple wanted to kill PWA’s, they would have done so worldwide. There is absolutely nothing preventing them from disabling them in the US and Canada (and much of the rest of the world) today, but they haven’t — they’re only disabling them in the EU.
Except they aren’t. Sure, PWAs may be slightly more disadvantaged on iOS/iPadOS than they are now, but they haven’t been “destroyed”. And they continue to work exactly as they did with the prior iOS/iPadOS release in all the rest of the world.
Everyone seems to think Apple is playing some sort of 4D Chess to kill off PWAs — but if Apple wanted to kill off PWAs they could just disable the functionality completely globally tomorrow, and they’d likely face no repercussions for doing so. They don’t even need an excuse to do so.
I’m not claiming that Apple is acting honourably here; merely that if they actually wanted to kill PWAs it wouldn’t require some sort of Rube Goldberg machine-style planning to do it. There is no conspiracy here.
