As for the Advertisements, I do not have a problem with a small straight forward ad in the footer or a link to your site. I think the problem with the meta tag ads is that you are using this SEF component so that you can control the meta tags, and then you realize there are ads in them. I think if you wanted to include a banner ad of some sort, everyone would have less of an issue with it. It seems sneaky to people the way that the ads are in the meta tags. If you want to have your ads in a free version, I feel that is OK, just have a banner or text ad instead of the meta ones.
