That’s also false. The GPL doesn’t only restrict non-free licences, it restricts any licence change on the derivative work. If I fork a GPL project and want to redistribute my changes with a free licence such as MIT, the GPL will prevent it to protect itself. It’s an authoritarian licence that doesn’t respect your freedom.
The only “freedom” the GPL infringes on is the ability to take the freedom the code originally had away from an end-user.
