In the same vein Matt Cutts has explained how Google helps hacked sites. His definition of "help" is a bit flaky, but the intention is good- and "no", the road to hell isn't always paved with good intentions- in Google's case they're doing the right thing, but calling it the wrong name.

They're not helping hacked sites, they're protecting the rest of us from the fallout of hacked sites, which is substantially different. What they do which is pretty cool is that they notify you when they have banned your site, and why. So, if you're oblivious to the attack Google are doing you a favour- they're absolutely not obliged to, so be grateful- seriously.

Google also provide self-help resources so that you can pick yourself up again:

My site's been hacked, now what?

BTW the guy who sparked Cutts' response, Ryan Stewart, still has an issue with the way Google manage these scenarios- and by the looks of it he is a little naïve e.g. "But I realized last night that Google is holding all the cards"- still moaning even when he gets commented on by Cutts, and a linked blog reference too- some people!
