The Policy is very clear in that point:
All packages in the Debian distribution proper must be freely useable,
modifiable and redistributable in both source and binary form. It must
be possible for anyone to distribute and use modified source code and
their own compiled binaries, at least when they do so as part of a Debian
 It is OK for there to be a requirement that modified versions carry a
warning, or that they be released with a different name or version number,
or something similar, because we can comply with this requirement if
So the Policy explicitely (see footnote) allows programs with licenses as
of "TkRat" to go into the main distribution. Of course, we have to change
