Every major app spies on you. Every web page, every app and even every operating system spies on you. You can't escape it.
Hardware as well. All network cards, cpus etc have unique ids. Sales records are kept and tracked. Printers save everything they print etc.
And it has been like this for at least 20 years. It is amazing that few know what akamai are but I hey make a point of not being noticed, like all data brokers. You live in a super charged version of a fiction where all info can be bought by some guy in a long coat. Reality is, your info is for sale daily to anyone that fills out a web forum and is willing to pay.
