A consistent theme throughout the article is that he's actually more interested in teaching people to write C well than fight with pedants. He's not torching his book, he's updating it and removing the contentious chapter. "let's write better, less security flaw prone C." is exactly what he's trying to say - the "don't write C" bit at the end is more about it being a dinosaur than a childish huff, though there is a little of that in that comment.
