Agree, Apple had the least incentive to monetize your data. Amazon will use your data to sell stuff, but they probably not going to share that to others. Google and FB are all advertising companies that they relies on reselling your data for targeting, with FB being the more aggressive one for you know, growth.
Neither FB nor Google "resell" your data. They use your data to put you into categories. Advertisers choose which categories to advertise to, and if your data puts you into one of those chosen categories then you're shown the ad.
You will be amazed how flexible they allow advertiser to specify the criteria, and how easy that with a handful filters they can target as niche as tens of people in the same area as a cohort.
I'd suggest you turn of all the personalization ads option they provided so that you can avoid to be precisely targeted
3+ years ago, their Graph API provided much more information than it does today. App developers (CA, in this case) used that open API to get information about the app user's friends, and then stored that data on their own servers (which is and always was against Facebook's Terms of Service).

Nobody reads TOS.
Car analogy: leaving you car in a bad neighborhood, unlocked, key in the ignition, door open, with a "do not steal or we will send you a threatening letter demanding our car back" note.
To the GP's point, the fact that Facebook has stated recently that it will reduce the information provided to third party apps shows that there was still a bigger leak than it cared to admit all along.
That doesn't make sense. By your reasoning, Google is reselling your location data by allowing Android apps to access it after getting your permission.
Apple makes it pretty clear that they don't use the data that hits a server to identify you:
> When we do send information to a server, we protect your privacy by using anonymized rotating identifiers so that searches and locations can’t be traced to you personally.
A much more nuanced and detailed explanation of what I was trying to share. Thanks for that. Wordsmithing isn't my strong suit. Your wording is exactly my sentiment, and better stated.
