I would say no.. because if the whole geohotz thing illustrated anything its that while you might own the hardware, Sony is the only owner of the software, specifically PSN. So Should sony be rewarding for failing? No. Will they? If the way that most large scale corporations exist is any indication, they yes, they will be rewarded handsomely for the PR campaign to make it appear as if ANON is bringing them down, when they are intentionally doing it themselves.
I hate to say it, but I am really starting to dislike Sony. Which is sad really because I have owned 3 consoles, multiple incarnations of the walkman, Home stereos, home speakers, Car CD player SE phones and have always sort of touted them as an organization. However the way they have been for the last 5-10 years has gotten progressively worse with the last 2 years being blatantly so.
As for the notion should the players be rewarded for an outage? Sure, why not. Grant players an inconsequential amount of credit towards PSN store. I mean its not like they are loosing anything directly by doing so, Its like selling air.
