I find this very surprising.
The first sentence of the article states that about 60% of men are single, and only about 30% of women. There's about equal men and women, so that would mean that 30% of women are dating each other, or are in relationships with multiple men? That's discounting men dating men. I find that surprising.
There's a big difference between a startup not managing and advertisers pushing billions of funding into creating this kind of thing. I very much agree with the author on this point.
