If his definition has shifted, it might be entirely correct to say he's wrong.

You can also accept his general definition but validly disagree with how exactly to apply it.

Inventing a term gives you a lot of authority but not total control over what it means.

Maybe the original founders yes, but the board and the decisions they make on how it's governed now is not the same group. That's like saying the original authors of the constitution never meant for it to be a living and evolving document. I don't think they ever intended it to be the one and only definition of the term and licenses.
