Licensing only the source under the GPL isn't unprecedented, but I think
it's a bad idea.  It makes people unsure whether they can distribute
recompiled binaries under the GPL.  This case is even more ambiguous,
since the EULA isn't clear on whether it applies to binaries, source or
both.  There is no source-only distribution, so I think the OSI logo is
particularly misleading.  There's no way you can easily (there is an SVN
archive) download a completely Open Source version.
