And I read a lengthy article about Chinese reverse engineering of
electronic products where they swapped out some parts for better
performing parts to improve the product. I doubt this happens in all
cases but I certainly don't think the two (using and improving
something existing versus starting something from scratch to achieve a
good implementation) are mutually exclusive.
