Please understandnim asking this question from a genuine place. I dont want the quora answer, i want the tech savvy, security expert minds of my fellow lemmings. If thats ok?
What happens to this data? What can/do they do with it? and why are so many people concerned about google tracking them?
Do i as an average user need to be concerned?
If so, What sorts of things can i do to avoid being tracked? Preferably without too much comprimise.
If you comply with their interests, nothing. Once you do anything that even looks like being against their interests, they use this data. There are programs of called DARPA LifeLog which literally logs everything. They even create DeepFakes based on the data they collect, ofc, not officially.
Yes, never give any data more than you need to give and move towards free and minimal software.
