One issue for me is that it’s easy to check a box and then have no idea how to uncheck it later (or forget that you even can). On/off switches for permissions seem sort of reasonable until you imagine dozens of apps and dozens of different kinds of permissions. In iOS for example all you get is pages and pages of toggle switches for all apps to allow/disallow cellular data, which is annoying to manage and has no intelligence in its design. They should have better defaults, such as automatically allowing all apps using less than some reasonable amount of data and automatically inhibiting the data-firehosing apps when you’re roaming. There’s a lot they could do. Asking the user, in general, is a cheap way to just not think through the problem.
