I get what you're saying, but blocking websites via the courts is a clumsy and expensive workaround which obviously has minimal impact and probably zero revenue benefit to the people who make those TV shows.
Further more, to watch shows in Australia we must first find who has that show. It might be Foxtel, so you must sign up to Foxtel to watch that one show. That is not practical.
iTunes is better because you can buy one single episode for $3.50, but it's a shame that it's iTunes and not simply the people who made the show, able to offer it directly to consumers without needing to go through Murdoch's "sign up for our entertainment package" or Apple's "we only take 30%" bullshit.
Bottom line: I don't want to pay Apple or Murdoch in order to pay the TV production company who made the show. That just means the price will always be inflated, and I don't use those services enough to justify that cost.
