Permission systems should not be a stand-in for good parenting. Monitor you children's electronics, educate them on what the important things are and what they mean.
Obviously. But how are you supposed to monitor your children's electronics, when they are few good tools to do so, and how are you supposed to educate them, when the technology is designed to obscure the dangers?
The content rating systems should help parents make choices about what apps are acceptable. They should reflect whether the app can record information about the child.
Education and monitoring are important, but they're no good without experience.
Can you be more specific about what actions one would take as part of "monitor your children's electronics" to prevent these problems?
if you just want your toddler to access a couple of apps from your tablet, create a restricted account that can only access these apps.
What if I want something in between locking them down to a couple of apps, and letting them accidentally send contacts to some app maker?
Ideally, you should have more granularity in the permissions of restricted accounts, with the option to let the second profile install app but with a prompt for the admin password when a new permission is required or a payment is started.
Sadly, AFAIK, there is no way to do that.
Right, so that's exactly the sort of thing being asked for, and it's what got this annoying/useless "just monitor your kids" response.
