Haven't read the whole thread so maybe someone said this but:
1. DCC's schtick really is that they don't look like the product they support... So no need for them to use the "official" monster or power templates, or any of the "visual" stuff.
2. Since monsters have to be redone anyway to be legal, most common monsters are already available, and the idea of special monster powers can't be Copywritten... Only specific instance of said special powers... Combine that with the whole idea of not being able to copywright game rules...
3. Goodman probably realizes that anyone who A: knows who they are, and B: is at Gencon most likely knows what 4e is anyway so no need to have the official brand logo displayed in order to move product.
