Is Facebook a data broker? Reddit? Google?
The page refers to 500 data brokers, but I’d like to find the complete list they use.
There is a reason the FTC and DOJ force this companies to break up, except they have hordes of lawyers and the law will always be catching up to reality so it doesn't do much in this day and age.
That doesn't match the definition of data broker. It's also a huge stretch, as many companies have subsidiaries and different divisions that are separate legal structures.
If you want to be both obtuse and pedantic about it, the answer is yes to all three.
