There is an interesting story in the Washington Post:
I live in a country (France) where censorship is a big deal. It comes mostly from greedy celebrities; they use a legal system that largely favors them. Often, they find a compassionate judge to rule on the issue of extracting money as compensation for a supposed privacy violation or for some other unauthorized disclosure. Convictions are frequent and expensive and can lead to the seizure of a magazine or even a book. France has a long history of such practices. In the early '60s, the country was waging a colonial war in Algeria. Then, for the most avid news readers, the game was to get the weekly magazine L'Express at the kiosk as early as possible before French authorities seized it.
Imagine this scenario in a coming iPad era. An iPad newsmagazine publishes an investigative piece that triggers a legal injunction: Remove that from the publication or face a $10,000 penalty per day. No, says the publisher, who has guts and money (proof that this is a fiction): We want to fight in court. The plaintiff then turns to Apple (AAPL). Same threat: Face a huge fine or remove the offending content. Furthermore, says the plaintiff's attorney, thanks to the permanent and unique electronic link to your proprietary devices and the fact that the electronic kiosk now resides on the device, you must extend the deletion to each user's tablet. Just as you keep pushing updates and various content bits to these gizmos, you can push a delete instruction code.
See, this is exactly why I don't like Apple's "leash shoved up my arse" business model.
