If this is truly the case, I don't even see why we care about it. We
have nothing to win from attacking if the only change they made is the
EULA. Just ask them nicely to put the GPL instead of their brain-dead
EULA, I don't see why they wouldn't agree, they have nothing to lose.

I haven't downloaded the package (and I don't have Windows), but I
strongly doubt there has been no change done. The press-release claims
that their software is secure and fights piracy. It also states that the
donwloaded files are encrypted. So my guess is that they have modified
the input of VLC to descramble the files. I imagine they have also
removed the stream output capabilities of VLC, which would make their
DRM pointless.

That code would be much more interesting. Can anyone actually try the
software and confirm ?
