Excuse me, but most of the time I've seen a reference in the very "freebie product description" that lets me know if a product is designed to go with, or "complment" a commercial product. In fact, I can't think of one instance when that has NOT happened. Maybe you can show me one?! What's wrong with making a freebie that supports a commercial product? Once I've invested money on the product itself, I don't always have money to buy all the other supporting products, such as textures, or clothes right away. I am very thankful for freebies that help out in this regard.
