"you're paying for inclusion in Google"

That's stretching the imagination more than just a little.

Most webmasters are happy that Google accesses their content, because without it they would get far fewer visits.

Any webmaster that doesn't want Google accessing their content can set up the appropriate entries in robots.txt and Google will not bother them again. Nor will Google's customers.

Very few webmasters exclude Google, though almost all webmasters know they could if they wanted. That speaks enough by itself.
