Feeds into what "system".

Do you really think Google/Amazon/Apple/etc are handing over your Name+Phone number to say Spokeo [1]? I just don't think you get it. Your phone company is the one that is selling your data to anybody not FAANG.

It's easy to say some "ad-tech" are doing X, but actually get a whiteboard out and start with say Google and list what products of theirs collect what data. Then list the process by which say the USG buys its from Google. I'm very interested in what names for the processes are going to be because I really doubt you'll find any for the ad-platforms.

I understand US carriers and ISPs are the most guilty parties that are selling data to third parties. Maybe not intentionally, but we have seen in the past when third parties get access to user information hoarded by Big Tech for e.g. Cambridge Analytica.

Even the data that is collected by Facebook + Google, are mostly non consensual and we don't know what they do with it. Or it's like the classic gun to your head, to use our "free" services aka, if you don't pay for it, you are the customer.
