Download a flashlight app, then call your cancer or fertility clinic? Awesome, now some random developer has that information.
The permissions on Android are further weakened, with apps able to add permissions without any indication via updates. (So long the permission is in the same group.) It's well-known that all-or-nothing, say-yes-or-it-dont-work is a busted model -- MS proved that with ActiveX and Vista's plethora of UAC prompts. So it's very unlikely that Android's permission model and UI is accidental.
And even then, consider the rampant abuse in the Google Play store. It's hard to find small apps, like a flashlight, that doesn't request all permissions. Yet Google does nothing, and takes no effort to inform users that such apps are likely to be doing things the users don't want.
I've realized, unfortunately, Google is not a force for good. They're happy to protect users against other threats (like code execution exploits or SSL attacks), but they are actively working against privacy, openly hostile. Do no evil indeed.
Compare to when enabling "OK Google" where OK and Cancel are flipped.
I guess they couldn't fit it in on Android?
I am all for moving to Apple's model, but making this move while staying back-compatible is not trivial at all.
