HBO is the epitome of a content provider not merely entrenched in the cable/sat model of distribution, but owes its existence since its inception to it. They have what makes them happy, yet whine when the newcomer Nerflix has a very different business model that undercuts all of that. Gee, too bad.
I'm happy to wait, buy used DVDs, which gives me media I can do whatever I want with, and gives HBO (let me see, gotta go get the calculator) oh that's right: $0.
