People pay to host things on AWS. PSN is a free service. They shut down PSN because of the data breach. Their screwup was in allowing customer data to be stolen, not in closing the network down.
That said, I've been eager for PSN to get back so I can register my PS3 copy of Portal 2 to use on the PC and so that I could play Killzone. It's amusing that the only two titles I will probably buy on that platform in the entire year came out near the same time and were hindered by the outage.
Their screw up was letting the network be down so long, being hacked TWICE, preventing any of the game producers from earning money while the PSN is down, preventing their customers from playing games they bought, etc. etc.
