I think you touch on the right point but indirectly. You can generate more value with more data, so sharing more creates greater value. That's true internally as you say and also externally. But the competition question isn't total value maximisation, it's capture!

There might indeed be a case for saying that ad targeting (and comparable products, like insights) is a natural monopoly and should just use Ramsey pricing. Maybe! But then we should build that, not argue against privacy.
