Exactly. The copyleft side of me says you can't copyright instructions on how to bake a cake, or a fast route across a city, or a beautiful way to display colored pixels in a grid, or an efficient compression scheme for video data... because it's all intellectual, and not physical, "property". But society disagrees so a nice hack on copyright that perpetually keeps any of the above from being stolen and locked down by profit seeking psychopaths just early enough to the scene to make a buck, seems like the best interim solution.
