I don't think it's that hard to differentiate between a web site created to serve a purpose which is also monetized in some ways and a web site created with the only goal of making money.
I don't think it matters as long as the end user is happy. If its users is what is important for Google, let the users give an unbiased opinion, without any guideline, on whether a site existing for a purpose or for making money is USEFUL for them. There is even a probability that a site existing only for making money can satisfy users.
