My thoughts exactly. This seems like a preemptive PR tactic by Google. Think about it. If this is bill is ultimately passed, then Google is playing it smart by taking this stance now -- to help them look more innocent later - when they inevitably roll over and comply with the US gov't.
For hackerdom at least, it's good PR. Consider Sony's case, they might have shut out a large number of talented people by the way they handled the PS3 hacking affair.
The difference is that Sony's pr was negative. And while an absence of a statement on the legislation might disappoint some people, I doubt it would actively shut out a lot of talented hackers.
