You're not. Here's an okay starting point into the discussion: https://github.com/WhisperSystems/Signal-Android/issues/282
Another thing to remember is that (IIRC) -for approximately forever- Red Hat Enterprise Linux has been a Linux distro that's composed almost entirely of Open Source software, but prohibits folks who receive the binaries from redistributing them.
My memory of the mechanism was a little different but the trademark component is obviously a part. Something in the EULA like "If you distribute RHEL binaries without our consent, we'll cut off your access to security updates and patches ASAP.".
Regardless, people seem to forget (or perhaps never bothered to learn in the first place?) that the GPL doesn't care to speak to binary distribution, just source code (and -sometimes- build instructions) distribution.
