You know, capitalist food producers don't need to be evil. All they need do is keep tuning their food, and a blind process of optimization will lead to addictive foods that people eat until they're obese, because that's what maximizes profits for the food industry.

It's not much different for Facebook. A blind process of engagement and relevance optimization leads to a more addictive product that steals more and more of your attention.

It's also not much different for Google. A blind process of information gathering leads to a more privacy violating product.

Different companies have different optimization processes depending on their business models, and they don't need to be made out of evil or have malevolent intent to end up having (potentially) evil outcomes.
