I don't understand the notion. Google already censors anything they like with very advanced methods that even provide them with plausible deniability, high specificity etc. And I bet they're better than the Chinese at tracking literally everything you do online and connecting that with your real, offline identity, complete with your entire social network graph, your biometrics, SSN, income, race, personality type, political affiliations etc etc... And they already provide that data to governments upon request. Not a legal request, but an API request.
The only thing I'd want explained about the article is how it would be physically possible to track users more closely than they currently do in the western world.
