I don't think there's one right way to code a website. So I wouldn't look down my nose at someone who uses a perfectly good architecture that's merely different from the one I would have chosen.
That being said, there is such a thing as a wrong architecture. (And for non-trivial projects, the absence of architecture is clearly wrong as well.) The choice between several good designs is partly subjective, but some designs are objectively bad. So I think criticism (not condescension) is warranted at times. Wordpress being a good example.
