That is an excellent summary of my concerns, but I have to press you a little bit on this one: you're looking at the top layer of this, think a few layers deeper. And I'm sorry if this seems a little obtuse and byzantine, but you're going to get a lot more out of this if you do the exercise as opposed to me trying to instill it. Let me give you an example, taken from previous threads where I've discussed privacy issues:
Google regularly comes under fire here and elsewhere for their slights, both real and imagined, against privacy. Even the most stalwart Google apologists here can't manage much more than "oh well, everyone is watching you, and I'm willing to trade my privacy for their excellent services, you should too or you'll get left behind". For the most part though, the ready response is either "what do you have to hide?" or "you're not important to this big company".
When I push people to understand the level of Google's invasion of their private life, they seem to think it stops with what they search for on Google.com. Some people understand it includes parsed emails and texts but don't look further. Even the Apple fans don't think any farther than this, because they always use this incredibly lame saying "At Google - YOU'RE the product!". And you can almost hear them saying "ZING!" afterwards. Its ridiculous and it shows that they have no idea of what goes on behind the scenes at Google.
Layer 1: search information including search variations
Layer 1a: how fast do you vary your searches
Layer 1b: what do you click through
Layer 1c (mobile devices) : how long do you spend on a given page? How many times do you back up?
Layer 2: emails and texts parsed
Layer 2a: what do you receive and from who?
Layer 2a1: how quickly do you read the next message ?
Layer 2b: how fast do you forward, and what do you forward?
Layer 3: navigation data
Layer 3a: how often do you go where?
Layer 3b: who do you meet. how often?
Layer 3c: how long do you stay?
Layer 3d : what else happens in the area while you are there?
Layer 3e: who else is in the area, however tangential? How many times have you been near that person?
Layer 4: what music do you listen to?
Layer 4a: how often do you repeat this music?
Layer 4b: who do you share your music with?
Layer 4c: what purchases do you make while listening to what music, and where are you at those points?
These are just the first 4 layers available to them during the normal course of your day. By the time you get to the bottom of that short list, they know an immense amount about you. The behavioral modifiers I've listed produce an alarming amount of data on you, far more serious than "he bought this brand of toilet paper on the way home from this movie".
Google has done an alarming amount of activity tracking. Their Android phones will track you in Airplane mode with the SIM card pulled and the phone turned off. Proven story. Their response to getting caught is usually "That never happened. Ok, it happened but you misunderstood what was going on. Ok thats exactly what was going on but it was a simple mistake, a debug feature that should have been turned off. it'll never happen again." But it does, usually before the reporting on the current privacy breach is completed.
Apple now seems to have the beginnings of an equally nasty system happening. Back to my original point, look at my layer model explanation of Google's bad actions. Then use that same mode of thinking to see what mal use Apple's new tools could be put to.
BTW: don't forget Apple has now enabled MacOS to always phone home and report on what apps you're using, and when, and how often, and you get the picture. And anyone who produces a VPN for MacOS must use the new VPN framework that conveniently tunnels Apple home calls right through the VPN layer. Still think they're benevolent?
