this could be compliant, if the different configurations were actually
present in the GPL.zip file

that is problematic. They need to publish the complete corresponding
source code for each and every firmware version they publish. There is
no discussion about this, and I have successfully inforced this in the

Then it cannot be 'complete corresponding source code' accordign to the

Can write up your findings? Just a small text document which particular
sections you have compared, and why they cannot correspond to each
other? This is very important...

*sigh*. it's part of e2fsprogs, which is licensed under GPL.

Just a quick note: emails tend to get lost. From my experience it
helps to write real paper letters, directed to 'CEO' or 'board of

I don't think that I hold any copyright on software contained in their
devices. So far, I personally can only act if netfilter/iptables,
msdosfs and/or initrd are used.
For everything else, I suggest writing a detailed documentation about
yoru findings, and sending that documentation to all respective
copyright holders. If you don't want to locate the copyright holders
yourself, I could help you out.
