It sounds like more than a just a "style" disagreement.

In the discussion of C strings, the author is arguing that Zed's arguments are nonsensical, maybe even objectively wrong. I write a lot of C, and the author is right in this case about C strings and undefined operations. In C you must arrange your code so that you always supply valid input to functions, there is no way around it, and it is perfectly safe once you do so.

I'd rather see discussion of the actual arguments, rather than complaints about the article's tone. :)
