That's the thing about surveillance capitalism. Nobody is going to tell you when they use the data they have against you. When my insurance premiums go up, my insurance company isn't going to tell me that it's because I've spent more time in drive-throughs over the last 6 months. The employer who doesn't hire me won't tell me that it's because of a political opinion I shared on facebook 12 years ago. When a store tells me that their return policy is returns within 3 days and I need a receipt, they aren't going to tell me that they told the last person who asked them the same question something very different based on the score they saw from a consumer reputation service.
The data being collected by companies is increasingly used to influence more and more of your life, but you aren't allowed to know when or why. Amazon's data could be being used to show you certain items while hiding others from you when you shop at amazon.com. It could determine what prices you pay vs your neighbors for the exact same items. It could be used to push certain content on prime. It could influence what ads you're shown. Amazon may sell your data to businesses they partner with (like “Starbucks, OfficeMax, Verizon Wireless, Sprint, T-Mobile, AT&T, J&R Electronics, Eddie Bauer and Northern Tool + Equipment.”) and they too will use that data in whatever ways they feel will benefit them.
Amazon isn't collecting and storing massive amounts of data on every facet of your life just to ignore it. They spend the money required to gather and keep that data because it is highly valuable to them in one way or another. That might mean taking more of your money from you, or that might just mean manipulating you and trying to sway your opinion, but you can be certain that they're using that data every chance they get to their own advantage and you can be certain that they aren't going to tell you when they do it.
And that's just in retail...
