The "N" in that weird acronym stands for Netflix. The day they start selling my data to advertisers is the day I'm back to torrenting. I feel like the author is so ad-focused that she doesn't even see this: the whole article is about ads.
Netflix is showing that you can make fantastic, super expensive content, even niche content, without advertising. To me that feels much more profound than "Youtube has more data about you than ABC so advertisers will prefer that".
