I get paranoia. If someone doesn't want to be tracked and not get a cell phone, or use only RAM in a computer or something... hey it's not my cup of tea, but if you don't want that data about you floating about, and you make that decision that's logical and fine. You see these companies, do track you, yes even Apple. Depending on your (or my) moral compass it's either right or wrong, but that is completely irrelevant. What matters is they have hundred of pages of terms and conditions dozens of apps and proprietary kernel level code running in the background on all these devices they can and will do what they want in terms of tracking you.
You know where they aren't going to track you? In an API developed with the competition (For all intents and purposes it may as well be open source), where selling the other one out on lying about privacy would result in the long run in tens of billions of dollars in profit without effort, where you give government agencies access to this platform of sorts. If and when they are tracking you, they will do it without revealing it to their competitors and ALL THE GOVERNMENT AGENCIES IN THE WORLD.
And you know which toggle button will be the last to stop working on your iPhone? The one that disables the "tracking" app... if an app is openly a "Tracking app" the disable button will work. They didn't get to be trillion dollar companies by being stupid.
Are they tracking you? Yes. Will they continue to track you? Yes. Will they do it through a tracking API available to governments and their biggest rivals, when they can do it in dozens of other apps and millions of other lines of code?
Get real.
