I'm in the same boat as them, I honestly wouldn't care that much if all my health data got leaked. Not saying I'm "correct" about this (I've read the rest of the thread), just saying they're not alone.
It's always been interesting to me how religiously people manage to care about health data privacy, while not caring at all if the NSA can scan all their messages, track their location, etc. The latter is vastly more important to me. (Yes, these are different groups of people, but on a societal/policy level it still feels like we prioritize health privacy oddly more so than other sorts of privacy.)
