Third party data brokers
The third party data market is a swamp. Data gets laundered so you don't know who collected it and anyone can buy personal data if they are prepared to pay. That means organised crime, the Kremlin, stalkers, fraudsters, anyone can access it without identifying themselves. So I will be happy to see that go away. Strengthening Google and Facebook's position for advertising is a bad side-effect though.
