Very few companies disclose the fact that they have been hacked.
I did some contracting work for a multinational charity a while back, and they knew that a rootkit had been installed on all of their web servers (which accepted credit card donations). They didn't bother to fix it until a second hacker broke the webserver (preventing apache from restarting due to a second rootkit that kept port 443 open). When the website went down the servers were rebuilt, and a press release went out blaming the outage on flooding in different part of the country from where the kit actually resides. The charity decided that they would not bother securing the webservers as they considered it cheaper to just rebuild them every three years (which is how long they had been running in an unpatched state for - I don't know how long they had been compromised, but it was at least four months).
I'm sure that sort of think is common, and public disclosures are rare so I'm glad that Sony public announced their breach. They could have blamed the outage on earthquakes in Japan, they could have said the shut-down of PSN was to "Ensure the security of customers during the unlawful attacks being committed, thus far unsuccessfully, by an extremist fringe group".
Public disclosure by Sony (which was reported on mainstream news where I live) allowed me to report by credit card stolen. The only other information that Sony held was my address (which can easily be obtained legally) and a fake date of birth that I supplied.
I don't see any reason why I should be compensated for a free service not being available. I don't demand some free stuff whenever twitter is over capacity and I can't access it.
If you are concerned about fraud report your credit card stolen, take advantage of the free fraud monitoring services if you wish, and move on.
It highly likely that your details have already stolen from another company you've bought goods or services from and they haven't told you about it.
