No, they don't. You're spreading misinformation. If the service provider can see the data then it is not E2EE. There is no room for negotiation here. Let me be perfectly clear that any service provider that claims E2EE while having access to user data is committing blatant fraud.
That said, it does not appear that Oura ever claimed E2EE. The author is merely making it clear to the reader that this is not the case.
Agreed. Weird to see a bunch of posts trying to argue that E2E doesn't imply that provider can't see the data, at rest or in transit.
