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.
It’s called microtargeting, all big tech companys are sorting people in groups, just by their use of the service. It starts with simple things, for example: cats or dogs? And this goes deeper to your religion or sexuality, politics etc. Created mostly for advertising it got used by political parties. Check the Cambridge analytical scandal. If you easily able to sort the people for your target you are able to manipulate your targeted people.
Newest scandal for microtargeting came from the EU-Commission with the chatcontrol.
Cambridge Analytica stuff though I think mostly revolved around them identifying more vulnerable users.
I don’t consider myself vulnerable to this stuff (I may consider grandparents and certain friends a bit more vulnerable) - should I still be worried about them having my personal data? I obviously would rather they don’t have my vulnerable relatives data so they aren’t manipulated, but for me personally does it matter?
You not considering yourself vulnerable to this stuff makes you exactly the type that is vulnerable to this stuff.
