This is one of those stories that doesn't really shock you but could still pretty much leave you fuming. Although Sony has finally made PS4 users' dreams come true by making the HBO Go app available, a certain subset of that group is missing out on the fun. The service still requires console owners to authenticate their devices with their cable operator and while most companies have been glad to do so, one, unsurprisingly, refuses to budge. That's right. Comcast is still blocking HBO Go on Sony's consoles.
