I'm glad you're asking. If you notice no one has said, especially Zelda, that you can't do these things. Obviously you can. You have access to a computer. The question you should be asking is should you do these things?

Also, this a good list of false equivalences. Robin Williams, when public, was empathetic, emotional, and arguably humanist. His memory isn't a caricature from people who have never known him, as you would see from Star Trek holo-deck episodes featuring Leonardo Da Vanci. His memory is something that is deeply important to people who are living. Some of those people simply appreciated his art and his behavior. One of those people is his daughter. You don't get to say what is right or wrong here. No one's going to stop you if you want to make a video of Robin Williams taking the Siegfried Oath, but you should understand why it is wrong.
