I don't see it as a rant. He criticized Ubuntu for unwillingness to clarify the trademark issue. Correct me if I am wrong, but how I understood the article, what Canonical did was to take Debian sources licensed under GPL, created a product based on it, but now if anyone wants to do binary redistribution of their product [the right GPL license assures], they could be sued for trademark infringement. So in practice they made it non-free software [free as in Stallman definition of free].
