You are mistaken if you think Apple are innocent and that no such thing as spying by big tech exists.
Read what I said again, carefully. It might have to wait until you're not suspended though. Arguing on the internet is not wise, but everything I said is factual. Take it or leave it, the complexities of the algorithms and surveillance mechanisms are beyond what most people have any clue about, and what they fear is for the most part not what is actually occurring, but there is a very good reason people get ads when they mention something to a friend, and it has everything to do with what I mentioned: data brokers, telemetry, and social graphs.
I'll give one example: You mention to someone that you're interested in buying a certain type of television, and your friend happens to live overseas. You suddenly get ads for that exact model the next day. Clearly they were listening to your conversations. Not so, what is actually occurring is that Google's ad network (and partners) are collecting so much data and have such an infrastructure built up that they understand the two of you are connected (the social graphs), your friend looked up the TV to check it out and their browser sent dozens, if not hundreds telemetry data points out into the internet by doing so – which are connected to data brokers and also to Google itself. The connections are made via algorithms that have processed so much data on billions of people that they understand the weighting of the social graphs, and have dozens of data points about you and your friend which inform the algorithmic decision to serve you ads about the product the next day, even if you never even searched for it on your own network or devices.
There are documented in depth cases of exactly this happening over a decade ago, just look at your network traffic. Then consider many people use "free" apps that they give too many permissions to, or use apps like fast food which often need location, etc. and what's really happening is you're trading your privacy for a slight discount on goods, and all of that data you send out is aggregated in such a way that it is so impactful it
seems like they are listening to your conversations.
This doesn't even get into deep profiling, or things like transaction telemetry which virtually every purchase involves – from Google collecting gmail data on purchases, to your credit card companies selling your purchase information (or at least the categories that you purchase, if not the specifics), and tie all of that to wifi addresses, IP ranges, MAC addresses and UUIDs (if they can get them), etc. etc. The ad-surveillance network is deeply entrenched and active in almost every corner of the world, and real-time bidding technology is so fast with updates that you can as a seller of esoteric goods buy ads that will target exactly those few consumers who might be interested in your luxury furniture that sells less than 10,000 units a year, but it's worth every dollar because they get to the customer who was interested.
Or, it's perverse.
But it's damn sure not related to siri queries being reviewed to improve voice recognition. All of that is nonsense and BS. Apple doesn't need to sell your privacy for pennies, they already get most people using google and also get 20 billion dollars – that is enough. You can make a lot of changes, protect your network endpoints, use anonymized tools, etc. but you will never fully escape this larger system unless you are totally off-grid and don't use networked electronics.
If you're worried about the government or a state-level threat that's a whole different ballgame and I won't even discuss those things, but this is all baby stuff compared to that – and what's been referenced about the leaks from over a decade ago aren't even close to accurate as far as cooperation, but most people can't understand what I wrote above – they damn sure won't understand the nuances of actual cybersecurity.
