It would seem that the technology mentioned looks at videos and makes a determination based on that. Does analyzing a video make it medical data? What about the other "medical data" that Apple has? Besides complying with COPPA, what data do they have that's not explicitly opted into?
I simply can't see past the alarmist rhetoric of this post. Especially when the cookie banner doesn't give an option to opt-out, with the option "Ahh, that's alright". Only a little ironic.
