The contract indicates that private enterprise retrieves some of your data and resells the analysis of the data, or the behavior of Internet users.

If you look at the origin of this private enterprise, it is registered in the New York State Trade Register as an advertising company.

It is an advertising company that fights against its competition to dominate the market alone.
