If he had said "phase of matter" I wouldn't have objected.
It's sort of like when planetary geologists use the geophysical definition of a planet: sure, there's nothing wrong with it in their own field, but telling the general public that the moon is a planet, Jupiter's galilean moons are planets, Ceres is a planet, hundreds of Kuiper belt objects are planets, etc., really misleads the public in a way I don't support.
You're not talking solely to other condensed matter physicists here; you're talking to the world. What would you like them to understand, and how can you meet them where they are? (Remember, their starting point is likely to be: solid, liquid, and gas are the three states of matter.)
