Google's Guidelines do define Ethical SEO
Google's do guidelines define Ethical SEO, to some extent. I say this because ethics vary depending upon the situation. Not obtaining an unfair or unwarranted advantage over others, and making false representations are clearly unethical, and if you read Google's guidelines with that in mind, they are clearly ethical guidelines. That is, breaching them could, if you aren't caught, result in such an unfair advantage - a good example being buying links. Cloaking with different content? Keyword stuffing? All examples of false representations and clearly unethical.
The size and influence of Google is a mixed blessing. It's nice to have someone big enough that they drive some form of standardisation. To put it another way, instead of having 20% of sites following MSN's guidelines, 20% following Yahoo's, 20% following Ask's, 20% following Lycos's, and 20% following Googles, most people follow Google and most other search engines have moved broadly in line with this and accept those sites. What would you prefer? To have to juggle many sets of rules, or to concentrate on one and be confident that the other engines can't be too much different...?
