Not necessarily... for example, take the KDE case. It is GPLd, even if
the use of it necessarily violates the GPL because of the need of
linking to the Qt libraries. Now this could be solved by a change in
the licensing terms, which would be a GPL plus a provision for linking
with (and perhaps only with) Qt.
The problem is that, as many people contributed significantly (more
than two or three lines of code), every one of these people would have
to agree in writing with the change. The whole mess is better explained
in Debian and Red Hat press releases about their decision of not
including KDE.
The point here is that even if theoretically possible, it can be very
difficult to un-GPL a piece of code if you are not the sole author of
it. If there are authors uncooperative with your will to change the
licensing terms, or even too many authors, your program will be
effectively GPL for eternity.
Am I wrong about this?
