If you receive a GPLv3 licensed application from someone else who tried to add additional restrictions, then you can just ignore them, sure. However, this comes straight from the author, so what you actually get here are two conflicting rules given by the copyright holder. I'm afraid this can not be considered free unless a relevant jurisdiction's court judges otherwise.
