No trademarks in upstream source

Your problem, then, is that you are unable to copy the software without breaking the GPL !!!

I think it was Nintendo? - lost a lawsuit over "unremovable trademarks" probably thirty years ago. If removing the trademark breaks the software, then the trademark is "essential to the operation" and loses its protection.

But why is everybody so obsessed with defrauding their own downstream? Why is everybody so obsessed (in the name of freedom) with violating the GPL?

The GPL itself requires you - unless it's a verbatim copy! - to *prominently* *mark* *it* *as* *your* *own* *version*. This is the problem with Fedora - their own users simply had no idea it was not the genuine upstream article. That's a GPL violation!

The threat of trademarks is simply a way of enforcing the GPL - "If you don't add your own marks, you have to remove mine". That's not a demand to remove marks - it's a demand that you follow your GPL obligations!
