Google's Health Connect system doesn't share this data either (without a consent prompt for third party apps, off course). This is to the point where I wish it would just support some kind of sync, because two devices hooked up to the same accounts need a third party app to transfer the health info.

Apple is subject to the same laws Oura is. The competition is too.

I believe the Apple one is E2E encrypted so they physically can't give useful data. Thats the core issue with Oura here.

Apple's iCloud default is still to link the encryption key to your account password, with a bunch of extra steps if you wish to use your own key instead, just like Google does.

It doesn't really matter that the data is encrypted end to end if Apple backs up the encryption key based on a factor they already know (your password).
