True.

However, that is an example of the GPL.

Ii can agree that it's not explicitly present.  

In any event, the problem he's presenting is that we must choose between
"ambiguous, and contradiction free" and "unambiguous, yet contradictory".

I don't see the existence of that choice as a convincing reason to accept
the contradictory option.

That's one way of looking at it.  It's not the only way.

Any lack of consensus doesn't mean that the viewpoint isn't
a way of looking at it.

And, again,  the existence of a choice between "ambiguous but
contradiction free" and "unambiguous but contradictory" is not in and
of itself a reason to pick the contradictory option.

Ok.
