Facebook already knows where you live and what your interests are by what brands you like and interact with on actual Facebook or by the account you've linked to your home console to share your screenshots etc. The value of ad companies knowing 'your hand size', 'how fast you're moving' or 'how your body moves in general' seems not very important.
You seriously can't tell how your performance in, say, a Fitness game could be used by Facebook for countless things,
like exchanging that data with insurance companies so that they can build a more comprehensive profile on you and how to deny you coverage?
I'm sorry if I come off as aggressive but...how naive are you guys? What do you think the central business model of Facebook is? It's your data. It's knowing everything there is to know about you and using that data to manipulate you into buying, seeing and interacting with exactly the things they want you to buy, see and interact with. What do you think why this is so relatively cheap? Because gaining that data is infinitely more valuable than anything a consumer could ever pay them. Why do think there are all these restrictions around how many devices you can use, how you HAVE to bind it to your FB account? Because the data is the point.
We know all of this! It blows my mind that in 2020 there are still people going "Eeeeeh, what could the company that completely dissolved and changed the fabrics of our society, which central aim is to know everything there is to know about everyone, steering "engangement" and their everyday lifes into the directions most helpful to their main cause - which is making more money and gaining more influence - what could that company POSSIBLY do with data about how I move, what I am afraid of, where I look and how I behave in a multitude of situations from a system that is literally supposed to simulate reality around me?"
Have you guys completely forgot about
Cambridge Analytica and any other of the dozens of scandals Facebook was and is part of? How the 2016 election was won by a racist fascist by his cronies carefully manipulating and using the systems put in place by Facebook to deceive and lie and spread conspiracies? Your "data" - meaning knowing everything there is to know about you - is literally the most valuable resource in our society. It allows to manipulate, to steer, to encourage in ways you could never imagine or even notice. Funny one-liners about how that ad you just got REALLY didn't fit your taste, lol, how bad could it be, come off as incredibly ignorant to me.
