I have a friend, oh, who we'll call Sean, who’s a brilliant patent agent/intellectual property guy.*
We’re getting T-shirts made for our ball hockey team (the Retired Superheroes), and I designed the logo with the Superman S on it. "Sean" told me that he couldn’t order it or ship it because it was a copyrighted image, and his IP business just couldn’t do it in good faith, as his company's name was on it as our sponsor. So I put stars around it. Then I sent it to him again with a balloon covering one of the edges. Then I put it on a pink background. For someone that’s known me, literally, my entire life, he was surprisingly frustrated in his explanations of why it still was copyrighted. So I added glitter.
People are fun.
