I assume OP is referring to the methods Google uses to keep tabs on people and then sell the data to advertisers and who knows who else. Technically users consent to allow Google to log every step you make (literally) when you use it's apps, online, or hardware. But of course most people don't read click licenses and even if they do it's still really hard for many to grasp that Google could be tracking them even with their phone's WiFi, Cellular, and BT off (eventually it has to go back on). Google isn't really forthcoming about all this. It does the minimum education about what it does possible. Facebook is only slightly better, so it's not just Google. But this is each's business model. There is a reason Apple sells "security" as a feature. Apple's business model does not depend on data collection. Unfortunately, Siri lags where, say, Alexa excels, on convenience and being more open to developers.
