Forget it: this guy is a "brick wall". Just notice how he repeats the GPL
forces somebody who makes modifications to distribute those modifications. We
have already told him tens of times that it is plain wrong. Twice only in
this thread (by you and me).
He already told us that he loves permissively-licensed software because he
can make proprietary software from it. He now somehow wants us to believe
that when the software is called "plugin" or "enterprise only", then it
suddenly is OK for it to be proprietary.
And for the record: I am not in a European country (although I am not certain
why it would matter; can't Europeans be right?; Is it plain racism?).
