I think the piracy marketing effect works especially well for iOS because not all devices are jailbroken. If Alice jailbreaks her phone, and Bob doesn't, Alice can show Bob her pirated apps, but can't easily share them with him. If Bob sees somethings he likes, he must buy it. The same might be true for game consoles, but probably not for PCs.
