Well yeah, but without observable facts, this is just wild guesses or paranoia. Considering the regular news about weaknesses in anything from Safari to iMessages, I have a really hard time taking these claims seriously. The storage and processing of health data is documented, and they do not leave the device or the Secure Enclave (unless you accept it, e.g. during a study).

Not at all. What you are saying is that you don't want to lock the front-door because nobody has illegally entered your house yet. In contrast, I want to lock my front-door for obvious reasons. No paranoia. It's just a different mentality of dealing with security.
