According to the Wall Street Journal:

South Korea today passed a bill that bans Apple and Google from requiring developers to use their own respective in-app purchasing systems, allowing developers to charge users using third-party payment methods

Now what? How will Apple respond? Will they create a different version of iOS for South Korea? Can they simply appeal this law, if such a thing is possible? How is this going to help other countries and parties to go after Apple’s practices? How much time will Apple be given to change its practices? Three months? A year? South Korea is probably a small market for Apple compared to other places in the world, but this new law seems like a tsunami in the making.
