Who builds and maintains the infrastructure? When a new internet feature needs to be added to the console, its up to the publishers?
No.... The publishers need to focus on games... That's it. The console manufacturer has to build the APIs and maintain the network. They hire the staff and the programmers.
People gladly pay for cell phone service, cable, internet, music, Netflix, etc. at far higher rates than PS+ or XBL. I just don't understand the reluctance to pay a very reasonable fee to the manufacturer so that they can maintain, support, and upgrade the online infrastructure.
