Granted, it would have been powerful if the author had called out (or was allowed to call out) Glamour's hypocrisy on this matter, but I think the fact that they're talking about the topic at all is a step in the right direction.
It is not wise to bite the hand that is currently feeding you. And I don't mean paying the author - I mean running your article. If Vogue will run it, let the reader notice the irony. If you call it out explicitly, Vogue (probably) won't run it. If you actually believe what you're saying, that's kind of counterproductive.
