Earlier quoted context omitted.
It was (still is?) a common practice to grant all permissions when installing an app from Google Play. Most people don't even look at the "annoying" popup that lists permissions to be granted and just press "accept" without ever reading it.
Well it's not like there's any option to deny them. You can only not install the app, unless the app chooses to build for the Android 6 permission system.
That's what I actually do. I refuse to install apps that require broad permissions not related to their primary purpose. Though I do realize that I belong to that insignificant minority group of users.
