Not that I personally would ever switch to iPhone because there is still a lack of sideloading open source software; but could you just not use the chat gpt integration?
It seems they are actually trying to not data harvest with all the AI stuff, there is quite a focus on privacy respecting server architecture and clearly defined conformations for the user for when something runs off device, or even off of Apple’s cloud (e.g. Chat GPT). I believe they even made their backend third party verifyable (although I’ve only seen their claims about this, I haven’t actually followed up).
Anyway, plenty of reasons to dislike apple, I’m sure they still collect data, but why not just ignore the Chat GPT functionality?
Us lemmings will never be comfortable with this level of centralisation.
