“Surveillance” isn’t very profitable; Google ad targeting isn’t even good and when it is good it doesn’t need your data. (For instance, if you search for “buy ps5” they don’t need a secret profile to show you ads for a PS5.)
The reason their ads make infinite money is they’re the best at serving them, they’re vertically integrated, and their ad auction systems are set up to cheat in their favor.
