Because he knows how to do it and because he is actually willing to put the hard work to do it. Also because he earns 30% of your ad revenue, so he gains something from it. As for the comments, I actually worked with him before, and I can say that I don't really get why anyone would say he is not a good choice. He is a really honest and professional person and you can rest assured that things will work out properly if you join his network. Most people that dislike him do so because he is really honest about his thoughts and because he has some controversial opinions about this community as a whole... Which is understandable I guess? Though that doesn't say anything about him as a professional. In any case, if you're worried about working with him because you think he might pull your leg, don't be. He really is honest about how he works with others.
