I get that...what irritates me is they don't do the same with Safari. With this logic, one could complain that the alphabet isn't kid safe because you can make naughty words out of it, or that a clock app promotes pot use because it reads 4:20 twice a day. A 17+ rating applied on such general grounds really creates a false impression about the products it's applied to, suggesting they are somehow more likely to expose the user to objectionable content and thus hurting sales.
