[knghtbrd@debian.org: Re: Interesting Licensing Issue -- Crafty]

Don't ask me how I missed not redirecting this message to -legal, I was
actually thinking about it as I was pressing the little reply button.  In
any event ...

If they are removing the copyright, what they are doing is already a
violation of international copyright laws.  And it's quite probably also
fraud as well.

In both cases, no.  What can be done (and should be done) is to make it
obvious in the license that such modifications involving just changes to
the name and copyright notices are not permitted.  This is reasonable
since doing so anyway is against Copyright law anyway.  Anyone who does
so is then notified that they face civil and possibly criminal charges
should they attempt this sort of thing.

It's sad that people would try to do this sort of thing, but
unfortunately the goals of Free Software prevent much from being done
about it.  =<

Eric Raymond:  I want to live in a world where software doesn't suck.

Richard Stallman:  Any software that isn't free sucks.

Linus Torvalds:  I'm interested in free beer.

Richard Stallman:  That's okay, as long as I don't have to drink it.  I
don't like beer.
