Wow...if your pockets are deep enough to take on google's army of lawyers, you really don't need the free traffic, do you?
That's honestly what it looks like to me as well. The moron who bought himself to the top of the serps in my industry (via paid links from high PR/unrelated sites) has been effectively zapped. Too bad, so sad.
The half dozen or so scraper sites I've been reporting for the past 4 months or so got zapped as well. So long, lazy morons.
Frankly, even without the fact that our site was finally released from the sandbox (or whatever), these serps are pretty clean. Only 2 spammers in the 1st 30 results in my industry.
I should also note that my oldest (hobby) site in a highly competitive category (45 mil+ results) hasn't budged.
