Google did not become this rich by selling potatoes. Also, Google is not your kind father who provides without any expectations. Google is data-hungry and it takes care of you so it can get more of your data. Imagine a farmer who takes a good care of its cow.
The farmer doesn’t love the cow. The farmer won’t take care of the cow for no reason. It’s the milk and at the end, the meat that is important. Google is the farmer and you’re the cow. You may turn off the data switches in your privacy panel in Google settings but it doesn’t mean that Google will respect your privacy and choices.
By signing up you agreed to the terms of service and Google can change them whenever it wants. Let me tell you something. By switching off those options, you only told Google to stop providing personalized services to you; it doesn’t mean that Google will stop receiving those information and data.
Google, Facebook, Microsoft, IBM, etc. are companies that work for data. It’s the data that matters to them not you or anything else. Data brings them money and it’s money that is worthy for them, not you. Don’t trust Google or any other service that collects your personal data by default.
Don’t get fooled.
