Except it is allowed, in section 7. Section 7 is not a mistake; it
means exactly what it says. This is an exception to the broad

You are incorrect. Extra permissions can be removed at any time.

I think it's obvious. Otherwise, people could just make trivial
modifications then do it; thus, this distinction is pointless. No other
part of the GPL requires modification.

The goal was changed, or you interpreted the original goal wrong.
Again, your own footnote makes this obvious.

No, it can't. It allows removing extra (beyond what GPL itself grants),
for modified or unmodified versions. You've provided no evidence for
any other interpretation.

I know no one else who finds this part confusing.

I think it is clear what the GPL allows. Do you have any specific
questions (other than removing permissions)

Copyright and patent. Copyright and patent holders have a very broad
right to license their work as they choose. GPL is one such license.

If he is part of the same organization as you, and it is the
organization that actually holds copyright, he may not have permission
to release it (the GPL doesn't apply to "internal" distribution. In my
comments below, I am assuming you and your "associate" are not formally
affiliated, and you hold copyright on the cool program.

You released the physical code to him. But GPL is a public license
(hence the name), so the license applies to all third parties. This is
the meaning of section 10 (Automatic Licensing of Downstream
Recipients), which states:
"Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License."

The original license (still in effect) comes from you. The sublicense
comes from the publisher, who you have given permission to remove extra
