This is precisely why I refuse to buy a Tesla. Because both of these companies are treating your purchases like their own personal property. They can install whatever they feel on it, all in the name of progress and wonderful causes. They don't care about the fact that you purchased it and it's yours, they just see you as a dumb user who is getting in their way to get more money. So it looks like my nearly 3 year old XS Max is going to be the last phone I bought from Apple unless they remove this idiotic nonsense from the new OS.
You know you do not have to update to iOS 15, right? Your phone will work exactly the way prior to iOS 15. It is entirely your choice and Apple have warned you in advance. iOS 15 will also be scanning text and numbers in our locally stored photos, remember? For privacy purists this is just as bad if not worse than CSAM. I personally will wait to see how this story goes and may stay on iOS 14. It’s not like iOS 15 introduces something incredible.
