nothing wrong with throwing their weight around, provided the peopel that matter (who, in my eyes, are the consumers) are treated right. I don't care if a few businesses suffer because of commoditization of their product.
there's a term in business for that. I believe the word is "anti-competitive".
They have a huge chunk of the search market but you can still use very good search engines like bing, yahoo, ask, aol or the awesome duckduckgo.
Google is continually tweaking and improving the design, speed, results and features of their search engine in an effort to stay ahead of the competition.
The reasons that people don't use the other engines are not because of google being "anti-competitive" but rather due to them offering a superior service.
While I wouldn't deny their right to do so, I also wouldn't deny that it often casts them as a bully.
