"It's completely inexcusable on any platform that something like that would be allowed, and, on a personal note, I've always hated the idea of 'in-app purchases'."
The thing most parents don't realize is that on iOS devices EVEN with Safari disabled (as well as 'Installing Apps" disabled so they can't just download some other wide open browser) there are many, many apps (seemingly content-neutral ones like the Weather Channel app, for pete's sake) with built-in browsers where kids can instantly go anywhere and see anything on the web with NO filtering and No record at all of that taking place.
So to keep their kids from pornography (or other adult content like violence, adult language, etc.) these parents eventually figure out that they can't purchase ANY apps with built-in browsers and that they have to delete EVERY single app they already have if it has a built-in browser anywhere in it. It doesn't make sense that Apple allows all these in-app browsers when:
1) Apps with built-in browsers completely ignore and neutralize Apple's browser Parental Controls or 'Restrictions' settings.
2) This problem inevitably decreases app sales revenue, in-app purchases, and even advertising revenue because if these apps didn't create a potential problem for their kids, so many adult parents would definitely prefer to purchase, keep and use those apps for themselves rather than having to delete them from all the iOS devices their kids might play on at some point.
3) There are already a number of apps where, if Safari has been disabled in Apple's 'Restrictions' setting, when you click on an ad or on any live 'hyperlink' anywhere in the app it just doesn't do anything (except offer to 'copy' the hyperlink address into memory so that you can go paste into an email or text message).
Apple should just make #3 the app design standard/requirement and then their 'Parental Controls' or 'Restrictions' would actually be more than a paper thin protection, especially since kids will always be more technologically savvy than most parents, however involved and intentional those parents are determined to be!
