If, as alleged, he emailed her at 10:50pm the night before he went to press -- and then said "she could not be reached for comment" and/or "she did not respond" -- he was being either lazy or disingenuous in that regard.
Her Twitter comments make her sound petty, but at least one of her complaints seems legitimate. She felt that she got railroaded here.
In the past if you published crap you lost the high quality advertisers. Now advertisers just go where the audience is, like the Huffington Post and Business Insider. In other words, all journalists are gossip columnists now. Even better if they wrote for free.
But I see a bright spot in all of this. In a sea of crap, good content might glimmer on the surface, wherever it appears. There's been a serious backlash among the tech and journalism communities against content farms and clickbait. People are, once again, experimenting with quality. Whether quality will be able to last depends on whether anyone can figure out how to make money from quality, and that's the unfortunate truth of the matter. Meanwhile, content farming is a gravity well that seems to suck every new publication down into oblivion, slowly but inevitably. A tweak here, an optimization there, a formula plied and followed, and before you know it, you're writing emotionally manipulative headlines and minimizing costs (and quality), like everyone else. But wow, look at those shares and pageviews! :)
I guess I still have hope. Otherwise I wouldn't be involved in journalism right now. For my part: I don't trade in gossip. I don't write clickbait (though typically, and depending on the publication, I don't have editorial control over my headlines or promotional copy). I try to be interesting. I try to be thoughtful. I try to have standards. I have yet to make a serious living as a writer, and until that changes, writing will remain a part-time gig. But I'm an optimist.
I suspect that whoever figures out how to monetize quality writing will do it by reaching back to first principles, rethinking the idea of publishing altogether. Trying to prop up a digital business on the scaffolding of a centuries-old business model makes no sense.
