I could definitely see Apple doing it on the App Store. If you jailbreak your iPhone/Touch and install one of the piracy app "stores" the whole process is just way too easy. I was perplexed why anyone would waste their time trying to steal a 99 cent app but after using the tools I understand. It's way too easy right now.

We can blame Microsoft for this but we should also blame the pirates. When piracy is hard and obscure it doesn't really hurt much. When these people go out of their way to create super easy methods of piracy and bring it to the mainstream they are forcing companies to react. They don't have to stop piracy completely but instead make it harder so the mainstream isn't so tempted.
