Worked at a major tech company as a data engineer, constantly warn everybody that major tech company is doing crazy surveillance, nobody cares. Told everybody my job was taking economists and research scientists python models, translating them into production code for data pipelines that would operate on terabytes of streaming data and it would change our recommendation system on the fly to keep you on the page. It was designed by academics to prey on basic human instincts. Tons more sketchy stuff, but I always felt like that was the most predatory. All we need to know was your zip code and gender and we knew how to recommend you stuff you wanted, and then people would voluntarily give us more identifying information.
