Yeah this popup really lacks a way to accept/refuse some permissions based on what seems logical for the app.
I would typically uncheck a lot of permissions on some apps, but since I can't do that I'll just click through if I really want it or cancel if I don't.
BlackBerry 10 has a similar implementation but allows you to choose if you want to enable that feature. When using the app, if it needs a permission you didn't grant, I believe it will prompt you again giving you the option to ignore it (at least that's how I last remember it..)
