I totally hear you - this seems SUPER SHADY. But I think the truth is it's really not. These data brokers are totally legit - legally. And also pretty common. Cell companies cell this stuff all the time to just about anybody. They're not loud about it, and people frequently freak out when they realize it. But this stuff happens ALL THE TIME. I also have heard that this has been a common technique amongst academic epidemiologists during the pandemic. Because it's actually all above board, and super useful. Still sounds SUPER F*NG CREEPY. But it's commonplace.
