Also, is Google itself funding New America, or is Eric using his own funds? I think there's a pretty big different, and making it all about Google just because Eric happens to work at Google seems unfair.

People are free to fund and support any cause they want in their own time with their own money. Yes, the person also happens to like Google a lot and doesn't want to see Google hurt, but I don't think Google should be held responsible for his personal actions.
