You can thank the head honchos at Harley Davidson for all the copyright infringement broohaha.
When Willie G and his crew started copyrighting everything from ape hangers to the sound a Harley makes and sueing anybody who even had a bar & shield in their advertisements without permission, everybody looked around and said "hey, if they can make money like that, so can we". Next thing ya know the model companies are getting nailed with fees to use a brand name on any piece in their kits. I'm not saying it's OK to copy anything without the owners permission but having to pay a users fee is getting a bit ridiculous.
