I worked at Amazon, which has a ton of data about your shopping habits that allow them to make targeted decisions on a customer's behalf. You know what? The vast majority of that data (at the time) came from observing customer behavior on properties owned by Amazon. In my mind, that's perfectly reasonable - what I do within the boundaries of their business is our shared interaction and we both have the opportunity to make decisions based on those interactions. The major exception for Amazon is affiliate links, which, for the business i was in, weren't used as data sources. Apple is not significantly different. Between Apple and me, who else knows our business and what does Apple know about me outside of my interactions with them (maybe more now with Apple Pay). For the most part, Netflix is the same. Sure they know what I watch, but why does that matter if they're only using it to improve their own business and make programming choices? Google and Facebook, on the other hand, blanket the internet with tracking beacons, read my email, keep shadow profiles (I don't have a facebook account, never have had one, but I'm sure they know more about me than I'd like), eavesdrop on conversations (I suppose Amazon is in that business now, too), track locations, steal contact data, trick people training their ML algos, etc. As is said, "If you give me six lines written by the hand of the most honest of men, I will find something in them which will hang him.", FB and Google have far more than that and a single bad actor with access to that data could make life extremely difficult for just about anyone in the world.
