While I don’t think it’s necessarily a true statement that companies like apple have access to everything, they do however have a closed system where we don’t know what they do and don’t have access to without them telling us. It’s inherently a dangerous idea to assume they don’t have access because we’ve seen with many examples that they indeed do, they just don’t have a need to.
Take tucker Carlson for example - the government got access to all of his phone conversations and knew he was going to Russia to talk to Putin. They admit it, and he’s got an apple phone. They do indeed have what they want, if they want it.
Any of these popular systems all have back doors and sell your information for profit without a second thought. Apple, Google, Microsoft. They don’t care about you, only how they can make money off you.
It’s unwise to assume otherwise.
