It's truly a sad age we live in. People are so brainwashed that they rather have other people make decisions for them instead of thinking for themselves. If you want to go the no porn route, then don't look at porn and monitor your children. Don't let companies say what you can and cannot do with a product you purchased.
I'm sorry, did Apple start blocking porn sites? No. They are restricting what materials they distribute through their iTunes store. If you want porn just use the Internet. BTW, I find it hypocritical if not plain ridiculous for people to cry for freedom by demanding that they be able to tell someone else(Apple/Jobs) what they have to do with their property both physical and intellectual.
