Also, it is true the CBC has a right to ask him to stop and that Apple has a right to remove the app at their discretion, but it is not necessarily true that CBC has a legal right to force him to stop. If the app is legal, Apple's policy of removing illegal content is being misapplied to this app.
Edit: Since I received a downvote from a petulant person I will try to explain further. As the writer of this piece explains, his app is basically a paid web browser that only works on part of one site. There is nothing wrong with writing a web browser, charging for a web browser and optimizing it for CBC content.
