Where do your answers on copyright come from? (Did you just make this stuff up)?
Several years ago OrigamiUSA engaged a copyright lawyer with over 25 years of experience in intellectual property to look into the question of how copyright applies to origami. He wrote up a more extensive FAQ for us, which you can find on our main copyright policy page, here:
You can also download from there a copy of his analysis with footnotes and supporting reasoning.
OrigamiUSA would welcome additional investigation and/or opinions from any lawyer with substantial experience in copyright law who would be interested in some pro bono work for our non-profit organization. Please contact the copyright committee using the link on the page above.
