"You can't stop the signal, Mal. Everything goes somewhere, and I go everywhere."
They're never going to stop piracy. It's like trying to play whack-a-mole. Movie companies would do a much better job if they stopped trying to squash any sort of piracy, and focused more on providing what people want, in the form they want, when they want it, at a convenient price. Some people will always pirate, sure, but 99% of people aren't going to ever bother if they can get what they're looking for conveniently and without paying through the nose for it.
I think you confuse what Hollywood wants. It's never going to become like Bollywood, where hits are fast and furious, and sell for rupees on the dollar.
Hollywood maintains it's margins on control. Like Orwell said "All art is propaganda". Wagging the Dog.
Unless there's a titanic shift in the market, Hollywood will continue to tell us what we want, rather than cater mainly to what is desired by moviegoers.
