This was their choice. They could have simply made it available for streaming during or after the show was broadcast, adverts and all. It isn't like most folks I know sit there and watch adverts on "regular" channels anyway. They can offer an ad-free service for a charge. When they don't offer such things on a fairly broad (global) scale, I don't see how they can be surprised when folks watch it illegally. And I seriously don't understand why the courts aren't asking the providers to do such things.
