I agree, but the intention is in general not overly clear, especially
when a licensor releases a work under the GPL and, at the same time,
does not make source available.
Self-contradicting actions leave the beholders in doubt about the real

Please also take into account that, in some cases, the authors of some
wesnoth-music files explicitly *refused* to release source (== their
preferred form for making modifications), and proposed, as a "solution"
to re-license under the terms of a license which does *not* have any
source-availability requirement. So, at least in those cases, their
intentions to *not* make source available is pretty clear.
See the previously cited forum threads...

I don't know how it would end up in court, in case someone [*] sues,
but I think that, in order to be on the safe side, we should assume a
strict interpretation of the license and consider those files as
legally undistributable.

[*] by "someone", I mean the copyright holder(s) of other parts
of the package, not the authors of the unreleased source files

Would you reason the same way, if we were speaking about a GPL-licensed
executable program, distributed in binary form, while keeping its
source code secret?

For the cases where it is clear that the source (== preferred form for
making modifications) is not what is being distributed and the original
authors explicitly stated that they do *not* want to release it to the
public, ..., well, how shall we call these files? "differently free"?!?

In some cases there appears to be an unwillingness to fix this issue,
as the authors actively refused to release source.

In other cases, the form originally used to generate the distributed
file seems to no longer exist. If this is really true, then the source
for such a file is clearly one of the actually existing ones: possibly
the one which is being distributed; if this is the case, no problem

I am also trying to be reasonable: I think that we should not set
precedents that qualify secret-source files as acceptable in Debian
main, just because they are not programs...

But here we are talking about the form that the author would actually
use for modification: in some cases, he/she states that he/she really
used that form and would still use it, but refuses to disclose it.

I think that we should strive to fix as many similar issues as we can,
rather than accepting one case, then another, then a third, and so
forth, down on a slippery slope...
