Companies also have their executives do things like tell you that they only use data ethically and responsibly, then turn around and sell it to the highest bidder.

A lot of times unless you're on a team or in a department that's doing this stuff for nefarious purposes, you wouldn't know.

Anecdotal evidence:

I worked in RPA (robotic process automation) for a large software company. We were tasked with automating a decision process. The decision process was completely benign. Something like a payments process. Pretty easy. We finished it in a few months start to finish.

We hand it off, it goes into production. A lot of back slapping and high fives happen. I go on with my work, move out of the company a few months later. About a year later, a guy I worked with at the company emails me a news story about a company using the RPA program we built to auto deny insurance claims for their clients. Massive class action lawsuit.

The insurance company had taken our script and just re-purposed it to auto deny a certain percentage of claims. I was shocked and dismayed that someone would use the stuff we built for their own shady business practices. It was a huge wakeup call that even when you're building something completely benign, a company can pay millions for it and reuse it to do bad things to people and you'll never know until its too late.
