The best way to stop Facebook is to stop using Facebook.
Social media is next level. It enables front row access to: social graphs, voice print, biometric data, subversive content promotion. Mental health with bullying, it’s extremely pervasive with the connectedness afforded by 24/7 networked pocket computers that have cameras. Sexting and revenge porn is a thing. Not to mention FB use in Myanmar https://www.cnn.com/2021/12/07/tech/facebook-myanmar-rohingy...
1. The effect social media has on people
2. What social media gathers about you
The comparison you made with video games doesn't delve deep into issue #1. With video games you play perhaps a violent game and the argument is that it might make you violent.
With social media the effect is different. Algorithms are affecting what you see, the echo chamber they create around you and can literary change your perception. This isn't even touching psychological experiments being done by companies like Facebook to see the effects to your mood based on what you see in your feed.
Video games haven't gotten there, they don't alter their behavior based on what you look at and do. They don't present other gamers that match your video game playstyle and likes and dislikes. They don't allow advertisements that specifically target your behavior.
Of course, pretending there are no sociological effects of the average person traveling 5X faster whenever they want is completely absurd but you are correct in what you said.
For example, Facebook is provided as authentification service on a huge amount of websites, meaning those websites send parts of your data to Facebook even if you don't use this authentication.
Seems to me, this is pretty much exactly how this works.
The SDK (recommended for login) is set up by default to collect information and installs handlers for app lifecycle events as soon as the app is installed. The default is to do this without requesting user consent.
A rough summary of the data: (Ad ID, device, locale, phone network, maybe install referrer).
To attribute advert -> install, Facebook ads pass on an encrypted blob containing campaign information to the Play Store, this blob is readable by the app, and is transmitted back to Facebook where it's decrypted.

In any case, this is not how it's supposed to work in oauth, and it's definitely not required for it to work.
I suppose developers could pretty much use any generic oauth lib for the login purposes.

> Automatic advanced matching will tell your pixel to look for recognisable form fields and other sources on your website that contain information such as first name, last name and email address. The Facebook pixel receives that information along with the event, or action, that took place. This information gets hashed in the visitor's browser. We can then use the hashed information to more accurately determine which people took action in response to your ad. After matching, we promptly discard the hashed information.
