They don’t sell user data for a very simple reason - it’s a crappy business, as you can charge much much more with to recurring sales for heavily obfuscated access to the data than just one off selling of said data.
When you think about it - initiatives are kind of aligned with user privacy (kind of, as there’s much more to the story than this simplistic point of view)
sort-of agree .. the accuracy, timeliness and completeness of any real-world data will change.. many comments assume some kind of perfect knowledge, which is never the case. Selling snapshots of current profile understanding is not only better business, but can also evolves with the enterprise over years; meanwhile selling raw user profiles as a whole is more like "damaged goods at a discount" for quick profit maximizers. This said, "surveillance capitalism" is rife and inherently a step backwards from a democratic society IMHO due to information asymmetry, secrecy and income generation.
The way I've always seen it is that they'd never directly sell user data because that is their most valuable and prized asset. It's what allows them to sell targeted access to users for so much money.
