In any case, the language in this exception is sloppy. It is never the
case that something external to me can by itself _cause_ an executable
in which I have copyright interest to "be covered by the GPL".

What sometimes _is_ the case is that the license requires _me_ to
grant GPL rights to my copyright. But if I decide to ignore this
requirement, there is nothing that automatically _causes_ a licence
for my work to be granted nonetheless. The fact that I will be liable
to the original licensor for having created copies without permission,
does not cause a license grant _from me_ to magically spring into

These sloppities lend support to the hypothesis that the exception was
not drafted by the FSF's usual license advisors.  Is it really FSF
