Vendor reasons and excuses: the bullshit "Intellectual Property reasons" Patents? Patents don't matter patents are open documents or they are misusing someone else's patents? Copyrights? no harm from using their documentation Trademark law? does not matter Trade secret? NDA only apply to person with the docs Translation: vendor is lying "Business reasons" / "Our secrets" Counterpoint: The Taiwanese vendors are doing great business giving us their secrets. "Disclosure of bugs" / "Crappy engineering" No vendor has ever given us this reason, but over time we have come to realize this is the #1 reason EVERY CHIP we rev-eng'd has turned out to be badly engineered
