that's the same in every shop
"Tesco don't sell massive dildos, do they?" No, but I'm sure I could find several down town that would be happy to sell me any size dildo I wanted, I expect there are lots of online stores that would too.
I'm not limited to Tesco, I can shop where I want.
And if I started making massive dildos I would not be limited to selling them at Tesco.
You think Apple is locking up the store just to protect you (because you can't protect your self)?
All they would need to do is give a warning when you install a non approved app. Something like...
'this app has not been approved by Apple, it may rape your mother, and kill your cat. You should only install approved apps if you want to be kept safe and happy by your friends at Apple' Continue?
That way people would not need to jailbreak their phones if they want to install a program that Apple will not approve of (like a wifi scanner for example).
