Of course I can. If it defines ti in such a way that it fails to accomplish
what it set out to accomplish.

I think I am beginning to see where we are seeing that language differently.
You are taking that language to mean that the aggregate must be at least as
Free as the GPLv3 if it contains a GPLv3 work. If that is so, then an
aggregate can only contain Free works. Fine.
I am reading it that you can restrict as much as any part allows. In that case
I am not restricting beyond what is allowed by that work.
Hmmm. But i am restricting beyond what is allowed by others.
I need to think on this some more. If this is truly the case, why are you
arguing against my language which is basically the same requirement?

But BY-SA does not match that. (Or defines mere aggregation differently?)

No it would not allow that combination. The copyright on the ARR work would
restrict the users Freedom beyond that the GPLv3 would allow (in your take.)
In my take to this point, it would allow it and that is why the language is
Which is it?

Or are you contemplating ARR works which will behave as Free works?
A makes a GPLv3 work. B makes and ARR work. C makes an aggregate containing A
and B's works. He gets a copyright on the aggregate. He does not intend to
enforce his copyright. Now B's behaviour controls whether C's aggregate is
acceptable or not?

It is more than just with the resulting copyright. It is what harm can be done
with the copyrights of the siblings.

Help me realize it then.

I was leaning your way until you mentioned a GPLv3 compliant aggregate with an

Do you maintain they are unrelated works? They are *being* related by the
compiler/aggregator. They may have begun as unrelated works, but they are now
