I LOVE my PS4, but I can't believe people are defending Sony this hard. The bottom line is Sony is providing a paid/subscription online service that is now down for the 4th day running. That in unacceptable. Period. It doesn't matter who is "actually" at fault. It's their service, and Sony is ultimately going to be held responsible for it working or not. The customer is not getting access to what they are paying for and that lands on the provider. And this isn't just a video game industry thing. This is the same in any industry.
Calling a spade a spade.
