I dont think its actually much of an exxageration. Every single tech company spies on people, Our own government wire taps us and spies on us. All our data is collected and sold without or knowledge or consent.
There was a dad who was mad at a retailer (I think it was walmart or target but idfk now) Because it was suggesting his daughter baby supplies and stuff for pregnancy, The dad was mad because to him this was them trying to sell his daughter on getting pregnant and having a baby and she was not even 18 yet.
A month later he found out that the algorithm of the stores website knew she was pregnant before he even did and he apologized to the store when he found out that she was pregnant.
