I think you missed what he was saying. He phrased it a few different ways in the blog and the comments, the clearest probably being: "(/dev/urandom || gettimeofday()) is a very poor source of entropy".
He was complaining about a particular usage he was seeing in the wild, not random and urandom, as he explicitly says a few times.
He missed the point, people complained because he claimed urandom was a poor source of entropy. That post is about using urandom securely, and he even shows that he doesn't know the difference between random and urandom.
