"Would I rather see an advert of a product I might actually want... or a tampon commercial?"

Perhaps there are covert uses to which this surveillance data is put, such as creating psychological profiles of individuals and 'nudging' them with their feed to take political positions. It is absolutely certain that business information could be used to capture economic activity by such means. There are thousands of examples of data analysts using the surveillance capability to stalk exes and collect dick pics. Not one example has been made public of contracts being underbid. Such amazing financial integrity in an industry so dedicated to deception is not credible, IMHO.

"Slavery is illegal and unconstitutional..."

No, it isn't. Slavery is allowed for governments that convict civilians of crimes. Read the 13th Amendment. You are not allowed to own a slave. All prisoners of American governments are legally slaves. This violates the facts of human rights upon which the Constitution is based, because property does not have rights, so enslaving human persons cannot be lawful.

Criminal justice is well named.

Thanks!
