I am not a lawyer but it looks like the creator of the project / repo did not put the appropriate license if they didn't want the designs to be used for commercial purposes.

"The design is open source and can be used freely for non commercial purposes."

The site's text matches the license, IMO. I'm not sure why the other guy said otherwise.
