I find copyright and patents very different, at least in the U.S. I support copyright, but not patents. Patents are used to stifle creativity and generate lawsuits.

Example, I designed something and was urged to patent it. It combines hardware, electronics, and in some iterations software as well. I released it copyleft instead. People make it in their garage, cottage industry sells it, a multinational profits from it.

The current designs are much better than my original. If I had patented it it might stagnate, or I could litigate and try to prevent innovation.
