Copy-pasting this from a comment I made a few days ago. I’m so tired of this misconception. Google’s business model literally disincentivizes selling personal data. The business model is built on selling targeted advertisements. Google wants to keep this data to itself because it gives them a competitive advantage in the ad space.
Selling your data would give competitors power in the marketplace. So yes, Google collects data and uses it, but no, Google does not sell your data. It sells targeting BASED on your data.
Very different, regardless of if it is any better.
