It is Google's business model. Last time I checked, they are pretty successful. It is unethical to attack an innocent competitor just because you have a gripe with Google. That kind of behavior reflects badly on anyone who makes his living as a webmaster.
Does success relieve one of responsibility?
Google can spend some of their billions for some manual checks.
