That was my interpretation too, except not restricted to “modern” websites. It sounds more like any website, modern or not, JS or not.

The part that is funny in that situation is that probably means web browsers are considered “app stores”. From a technical standpoint that’s actually pretty accurate (though they also handle running the “app”, unlike a regular app store), but has the fun consequence of making web browsers also “app store stores”. Most browsers can be used without an account though, so I look forward to the dumb antics companies with large legal departments come up with for this one.
