I would gladly pay $0.99 per episode to rent season 3 of True Blood in HD quality over the Internet right now. I'm sure as shit not going to pay $12/mo+ for HBO since they have nothing else I'm interested in.
That's the problem. At 0.99 per episode with no commitment you're not a reliable, profitable revenue stream. HBO and others really couldn't care about losing a customer like you. (No offense to you personally).
