"How about you start calling it what it is. It removes cash from the pocket of the creator - it is theft. End of."
Cept that is precisely what it doesn't do. It removes the 'potential' cash that might have at some point ended in pocket of the creator*. So its not theft. * as not all legit sales end up with money for the creator, and nor should they.
You're making the same mistake the studios do, assuming that every pirate copy is a lost sale. Which is utterly illogical, as its assuming most people want to break the law, which has been shown many times is false. Its also assuming that their desire to want the content means they 'will' acquire it, which is also false.
People have multiple sources, they might buy the bluray, or dvd, or maybe rent, maybe stream. They'll pay as much as they can afford, but if the producers have blocked one or more of these for their own narrow minded reasons then people might see piracy as an alternative. And that pirate market was created by the content producers themselves...
