I suggest that we never rely on that clause, ever.  First, this clause
cannot convey the intent of a copyright holder of an incongruously
licensed works nominally covered by the GPL, version 2 or later, but
carrying additional restrictions.  Second, if two clauses conflict,
the problem generally doesn't go away just because one clause says
that the other is invalid.

(The Python license stack could serve as a precedent, but there, the
licenses are stacked differently, the TOS is the most permissive one.)
