Well, I surf with JS turned off (actually constrained by NoScript) and pop ups are disabled, and I don’t see any unwanted stuff on google. And I only use the search engine, nothing more that they offer. So I don’t see how they make money off me.
Sounds good, it’s just they can show X amount of traffic to advertisers (via searches).
If people were to ban the search part as well, their traffic reports would sink and advertisers wouldn’t be willing to pay as much for sponsored ads etc., thus decreasing their revenue.
