It’s a lot bigger than just this though, because they buy data broker info, which isn’t included. I once read a piece in Harper’s Magazine, they bought these data brokers’ bullshit and looked at their own profiles, and they were very wrong on a great many things, wrongly labeling people as gay, (facebook tried showing me gay ads at one point,) and a host of other ill informed conclusions about us. Keep in mind, the feds, and maybe states now, buy this information to use against us. We should have some rights, but we don’t.
