On what basis do you say that?

That primarily happened under former editor Elaine Welteroth; she left shortly after Condé Nast killed the print edition, and it's my impression that TV has been moving back toward a fashion focus -- although a glance at their web site shows that they're still doing political reporting and op-eds.
I think this is similar to the Sokal Squared[0] scandal, in that a tribe (in this case purveyors of progressivism) will judge some work unduly positively.
Put another way, Teen Vogue's notoriety at the time was less "wow, this is truly groundbreaking journalism", and more "wow! Teen Vogue usually writes about makeup, but now they've gone all serious, and they said Fuck Trump! And Fuck Trump indeed! Go Feminism!"
I would argue that given your evidently gross misinterpretation of my comment, it is now actually you who looks hysterical.
But you did "air quote" for satire.
In any case, I think the point in the context of TV publishing and unpublishing the Facebook fluff piece is that doing that sort of thing runs counter to the more recent perception of them as politically savvy enough to understand how publishing a PR-provided article like that might look to their audience in particular.
Sure, I can believe it. Because facebook, and companies like them, routinely manage, via their PR departments, to get articles not different than that published without paying for it too. It's certainly the easiest way for a journalist/writer to write an article, from the press releases and interviews given to you by a company, provided on a silver platter. And there isn't a whole lot of money for articles beyond the easiest/cheapest way these days.
The division between "journalism" and "content farm" (write whatever you want that gets eyeballs, if you didn't lie about anything, that's plenty ethical!)... is increasingly a grey area.
Teen Vogue actually happens to be pretty responsible journalism that usually does better than that. But how or why would Sandberg keep track? I'm sure she knows that they got the article their PR department wanted, it literally does not matter to her whether they actually wrote a check with "for that article" in the memo line to make it formally 'sponsored content' or not.
