Quoting Anonymous on their involvement is a moot point. The lack of hierarchy and completely radical differing opinions of members within the "group" allows for confusion and varying ideologies. Since a press release, in the mindset of Anon, is released by an individual or a group of individuals, they may not be aware that a separate member did perform the hack. In the end no one really knows until someone pretty much steps forward.

If I just got my hands on a few million CC's I wouldn't tell my shady "friends" either. Not even for the lulz.

In fact, I'd be peeing my pants if I saw that in the SQL-dump I just downloaded through a couple of proxies.

I thought Anonymous apologized to PSN users for the collateral damage? Makes me wonder if they're just trying to save face after realizing the users were turning against them too...

"We realize that targeting the PSN is not a good idea. We have therefore temporarily suspended our action, until a method is found that will not severely impact Sony customers." -- Anonymous

Then they went on to say something about how Anonymous is a diverse group and they can't control everyone, blah blah blah.
