That's probably true, but not really what's newsworthy and notable here. I mean, yeah, Teen Vogue surely didn't mean to publish it like that.

But they did, and when they did Facebook promptly crowed about it and pretended that this was journalism showing (pause for breath) Facebook's dedication to honest media coverage. And it was a paid advertisement the whole time.

That's... well, just ew. And none of that has anything to do with CMS features that made the mistake visible to the public.
