If you need access to both apps from China and websites/apps from outside China, non-Apple devices have been difficult before this, primarily due to push notification infrastructure.

This makes it more difficult. But I don’t think it matters given how difficult it was prior to this.

What's wrong with Apple push notifications in China?

"non-Apple", i.e. Android

The problem is that most popular apps for Android outside Chinese app stores rely on Google services (specifically, Firebase) for push notifications.
