I don't think we should accuse the author of intentionally misleading
us.  I can see no reasons for that; instead he's stated that he just
doesn't care a lot about those legal things, and wanted to be sure to
not get bugreports baout unforked versions.  

Since the "You must provide sources" argument of the GPL is kind of moot
for TeX input files[1], I think he should be well served with the LPPL.

[1] Of a GPL'ed work, you have the right to get the dtx sources if they
exist.  But this is probably unenforcable in practice, because anybody
unwilling to produce them might just as well tell you he has lost them
and continued to edit the *.sty/cls/tex files directly.
