Turbocharged, I think you're confused about what "hypocritical" means. Google would be hypocritical if it said "Don't buy or sell links" and ran a link-brokerage business. Saying "Here's information that you may find useful, but don't abuse it" isn't hypocritical; it just shows that Larry Page and Sergey Brin had a naive faith in human nature when they launched Google 15 years ago.
As for toolbar PR, it may be imperfect (and outdated), but it's an example of the "transparency" that site owners and SEOs are always demanding of Google.
