ARCemployee That will be fantastic if the app communcation scope comes out. I have to apps using the app communcation channel for ads promotion. Blocking that channel will massively enchance both privacy and security protection
We'll see. But I think people may be assuming that an app that is blocked from talking to Google Play will just shrug its shoulders and go back to doing what the user wants it to.
However, some of those apps will crash and others will throw up some error message and quit. And why wouldn't they? If a game was written to show ads, that's because the game author wants to be paid by the advertisers. If ad serving is blocked, then the game author won't be paid.
I think IPC filtering might turn out to be mildly useful at assuring users that an app that is marketed as privacy-preserving actually is privacy-preserving, and at assuring users that an app that normally doesn't talk to other apps hasn't been taken over by malware. Those are useful. But I do not expect IPC filtering will convert privacy-invasive apps into privacy-respecting apps.
