I have passed by freebies marked "non-commercial" unless it's something really extraordinary. Not that I would ever be in a position to sell anything...it's just something weird about me. I don't suppose this really bothers the offerers of the freebies but seeing a big download count might make them feel good. In other words, if there weren't many downloads, they might think their freebie wasn't considered very good or something. My memory can play tricks on me but didn't this default setting come about from a big discussion nearly a year ago or something?
