I may give to others the permission to use the modified/redistributed
file under GPL-3+. This permission is what is usually called "License".

In that sense, the license is changed.

The license is usually granted to a file as a whole, not to specific
lines. If got got a changed file from me, and you revert my changes,
then you are still bound to the conditions that we agreed about when you
got the file -- these conditions are the "license". If we agreed on
GPL-3, then you are bound to GPL-3.

Just again this example:


This is a file that is initially copyrighted by Daniel Boulet (and
licensed under BSD-2-Clause). However, without any other change, it also
has the header

| Copyright (c) 2000-2007 Apple Inc. All rights reserved.
| [...]
| This file contains Original Code and/or Modifications of Original Code
| as defined in and that are subject to the Apple Public Source License
| Version 2.0 (the 'License'). You may not use this file except [...]

So, Apple puts another license to this file, probably without having the
permission of Daniel Boulet.

Would you accept such a file in Debian? It is clearly not BSD-licensed,
even if an unchanged BSD-licensed version exists.

When trusting the Apple Lawyers a bit, then this contradicts your
