Well sounds like they didn't go far enough then, they should cut all internet access so that users don't accidentally download malicious apps!
A user that wants full control of their own device should have that option available. There is no good reason Android makes it difficult to access its data folder for example for users that do want to mess around with that stuff.
Disagree, you have to remove that window to recycle the rest of the packaging. I specifically look for the ones with no window if possible
