There are many industries with similar, parallel, practices that are directly at odds with serving the "user." For example, groceries. A typical grocery store presents a selection of products in a grocery aisle. This presentation is not optimized to give the shopper the best experience, lowest prices, or highest quality products.
The products, and product displays, are optimized to extract the most profit from the shopper, often resulting in inferior products. Grocery stores also collect and analyze reams of data about individual shoppers -- again, not for the purpose of providing better value for the shoppers, but for extracting maximum profit from them. Want that data back? Good luck!
