Watched too much television. Thinks the FBI doesn't use the same tech and algorithms to monitor terrorists and threats that Facebook and Amazon use to track customer preferences.
You actually think Amazon customers are terrorists????!? HAHAHAHAHHAAHAHAHAHAHAHAHAHAHAHAHAHA! What does that make the Alexa service then?? A method to communicate with all those terrorists???
Gee, Sybil; do you really think FB and Amazon really have an army of people scrolling through orders to track their buying habits? Or do you think they use computer algorithms to collect, assess and process customer habits? Why do you think our nation's intelligence agencies aren't using the same technology to track threats?
Why are you asking yourself? You obviously don't know. You should ask someone like me. Since you are woefully confused, I will answer anyway.
Facebook doesn't have an ordering system and doesn't sell anything (although they DID acquire Oculus, a VR headset company, promptly destroying it). It DOES have Facebook accounts. I don't have one or use one. Facebook provides nothing useful to me.
Amazon sells many different products and also manages contracts with 3rd party merchants (which Amazon calls 'affiliates') that drop ship using Amazon's COW as an order driver.
The Amazon catalog is manually built (I know the guy that manages the team that does this) and it's search algorithm is rather lacking. It DOES try to use your past purchases as a guide, but rather sucks at that, too. They've tried to improve it, but it still rather sucks, often showing products completely unrelated to what you searched for.
Amazon does not track 'threats'. It simply tracks your purchases to try to guide the search engine for you.
This tracking DOES have one nice advantage: You can look up purchases you made even years ago to remind you what product you purchased should you wish to repurchase it, and their return policy is VERY good.
Another product of Amazon is, of course, the Cloud (they invented it!). Running under the name of Amazon Web Services (or AWS), this cloud offers an amazing array of services for people to use. Pricing is generally based on what you use, rather than an overall subscription scheme. The most common services used are Lambda, EC2, and S3s. The Alexa service ties into these creating thousands of 'skills' (Alexa programs) that you can choose from. Most skills are written by private individuals or 3rd party companies. Many websites run on AWS, and many companies use other services in it to provide specialized web oriented handling, message handling (such as email or SMS), translations, speech recognition, and database usage (AWS provides several choices).
AWS does track usage for accounting purposes, but also tracks usage for loading purposes. This information helps Amazon adjust their server structure to cope with changing loads, and guides them while writing additional services.
Amazon DOES have guidelines that you must conform to if you build a website that runs on AWS. Pornsites, for example, are not allowed and will be shut down. The list is not very extensive, and is pretty clear.
Now, you can live in whatever paranoia you want to, Sock. But Amazon takes VERY seriously the privacy of people using AWS and Amazon itself. Stored credit card information, for example, has only a VERY few people that even have any kind of access to it. It is much more carefully controlled, then say, Target. AWS uses a triple token security system (two are user facing) that generally prevents Amazon from accessing any of the data within AWS, unless specifically published (like a website page). You will not find better security then within AWS.
Bezos isn't stupid. He knows that if security is compromised on AWS or Amazon, that would cost him literally millions and may even mean the end of Amazon as a company.
So you go live in your little world of paranoia, Sock. The rest of us will happily purchase products on Amazon and use AWS.
