Silicon Valley: Mike Judge's new HBO series

The thing that’s confusing to me is why they are dragging their feet on having an independent streaming service. They have a huge catalog of original content, their shows are some of the most popular and pirated on the net, and they have the architecture in place since they already have a service they just tied it to you having a cable subscription. I am puzzled. I mean, they could charge as much as netflix or hulu, and people would happily pay it.
