This idea keeps coming up. There’s a few reasons it hasn’t happened:
1. To really leverage the personal data, you need to run it through a model and correlate it with ad inventory. Those are two things you don’t tend to want to deliver to an insecure client. Then you need to collect data on how those ads performed to update the model.
2. For all that, it’s still more convenient to manage GDPR opt-in. Don’t underestimate the convenience of centralized management.
