No it's just his same argument as ever. The GPL specifically addresses RMS' issues of software freedom. Choosing a different license ignores the topic of software freedom as defined by the FSF. That's all he is saying.
Look the GPL is a hard choice. It is very unfriendly to a developer who is looking to make a living on their code, since it makes selling that code as an artifact. It's not impossible but much more complex than if you just have a EULA.
That said if you remove that difficulty you neuter the GPL and weaken the point of software freedom.
I get why RMS pisses people off. He doesn't keep arguing for using the GPL to be an asshole, but because he thinks software users are more important than software developers. Perhaps most developers feel differently?
