This blog is stating that it is okay to get inspiration from other work. "Copying" has a negative connotation, but should have a positive one when it comes to art. This is how great artists get their ideas from. Inspiration.
"Everything is a remix"
This video goes against the American "copy rights" law. A product can evolve. As he says in the video, "everything is a remix." In art, I get inspiration from other art work I find on the internet or in museums. I don't necessarily consider this copying, I consider it transforming and designing my own product. Inspiration sparks every artist before creating their work. Every idea comes from somewhere.
