I agree with @filterframe The majority of the searches where users find their answers in Google and do not click through to your website are not actually searches for buyer/commercial keywords, so they won't affect you anyway. Also, Google is probably not gaining from this either unless ad click rates are going up as well. Also, they created the market, as @Gogol mentioned. Without Google, there would be no SEO or making money online. Lastly, take a look at the top sites online and you'll see a single site alone getting 10 million clicks per month. There's enough traffic to go round.
