This strikes me as defeatist. You can run GrapheneOS and pipe everything through VPNs for your phone. It's really easy, the phone does all the normal stuff except the constant listening ("assistant") thing, and it's way harder for anyone interested to spy on me. I don't run Google or Apple software.

If someone could get their hands on my data, it'd be a bunch of extra work to determine who it's coming from.

>>Some people even connect their watches, which monitor (or will soon monitor) everything from their heart rate, sleep schedule, oxygen levels, BMI, etc.

You can easily have a watch that does all these things but doesn't share any data, and you can be sure of that based on more than just promises. Open hardware, open software, local data storage and zero-knowledge for anything touching the internet. It's well within our grasp technically, we the people just need to demand it.
