Search depends on net neutrality. As a searcher, you already know how it feels to be blocked from results. Who hasn't performed a search where you clicked to some blocked or paid access page? Now imagine that on a larger scale, and search becomes an exercise in ultimate frustration.
Publishers play an active role in search accessibility. While this is taken for granted by publishers, all organic and paid listings link to page content they truly control. Without neutrality, it's possible that URLs could be filtered or treated differently based on still-undefined rules set by broadband providers.
The Big Engines are ready to fight. In July 2006, Google warned U.S. legislators that if broadband providers abused net neutrality principles, it would consider anti-trust actions. Google's position is still posted today, and we're pretty sure it has not changed.
