"Americans let the Patriot Act be passed into law, not Google. Stop blaming Google and start blaming your democratically elected government"
Just like Google is putting their lobbyists where their interests are in cases where government intervention (or lack of it) is hurting their business (net neutrality, open mobile applications, visas, wireless spectrum, etc), they should also fight against the Patriot Act.
If people don't feel comfortable using Google's products due to fear of government spying, they will restrict their search, clean their cookies, block adsense/analytics, etc, all of which will impact Google financially.
