Hello again buckworks. Thank you for the insight. I greatly appreciate it.
re: "but it's by no means the only place that people visit online."
I am not saying they are the only place people visit online. I am saying they are the only place people visit online to promote their online business. You can't argue that Google is not a monopolist in the advertising business.
My argument is that Google is not allowed to have a policy in place to block my kind of business, because they are in direct competition with me, and because they are a monopolist of my business' type of business.
re: "For instance, if the monopolist refuses to sell a product or service to a competitor [ME] that it makes available to others [EVERYBODY ELSE], or if the monopolist has done business with the competitor [in the past] and then stops [WHICH AGAIN, THEY HAVE WITH ME], the monopolist needs a legitimate business reason for its policies." (again, lifted from the FTC link above...)
Perhaps the courts would argue that google's vague "oh, you broke one of our million policies in this 10mb TOS page" is a "legitimate reason" but I highly doubt it.
P.S. Please note... I am not in the position of needing Google. I have answered that question quite elegantly with my free trial/affiliate program setup I believe. My site is currently flirting with the top 5,000 alexa domains in the world.
