Yes, you seem to be confused Bernie. You can redistribute under a
license however you like, usually without explicitly stating it. But
if you alter the source files or replace COPYING, you are *changing
the license*. That is a different act.
A more passive-aggressive means to your end might be to announce that
SugarLabs will only accept new contributions which are licensed
GPLv3+. That will effect the redistribution change you want, while
still (a) pissing off parts of the community, and (b) not illegally
altering the license on code you do not own.
