If they can't survive off of donations, then they don't deserve to exist. If they want to sell user data or search defaults, Mozilla should fork Firefox.

When Zuck said this, I could feel the smarm, but I respect his honesty, and I know what he's not saying. Mozilla is trying to spit the same game about its Google search default deal, as if that is the same thing. It's not, because when Facebook does it, it's a for-profit corporation selling out its users. When Mozilla does it, it's a nonprofit organization selling out its users to the single largest for-profit web property in the history of the Internet.
Google is a monopolist. They should lose the right to pay off their competition.
