Agreed, I would like to see some legal precident that proves GP's point.
Additionally, GPL only grants you "additional freedoms" if you're willing to reciprocate. If you want to use it in a closed source work, it very much limits your freedoms. The phrase "permissive license" exist for a reason, and it explicitly excludes the GPL.

It's the copyright law which prevents you from using GPL software in closed source works, not the GPL. GPL doesn't care about proprietary software at all, leaving it at the mercy of status quo. It only grants some additional rights to users and developers of free software.
