There's no problem with the product. The question was about morphs that look like celebrities. A big part of the equation is how the look-alikes are used. If your doing some political satire pictures then they couldn't do much. Create a picture with an Arnold look alike and the phrase "My favorite webpage is ______" then you could have a problem. Also the one selling the morphs could get into trouble. Careful wording and the proper disclaimers are required. That's what a lawyer is for.
