Yes Apple is willingly staying quiet about your iMessage backup being accessible by them. But it does not change the fact that iCloud Keychain is end-to-end encrypted with Apple incapable of accessing your keychain.
When I first learned about the iMessage backups being accessible I was a bit let letdown by Apple. But I never believed they were best in class for privacy. The iPhone's true strengths lie in the OS support and FaceID.
iMessage itself is pretty slick but if I want privacy, I use Signal. It also gives me a crossplatform messenger as I prefer Windows and iOS.
Same as with Microsoft Edge. It's my favorite browser now, but I do give up a bit of privacy for convenience. If I want the best privacy I use Tor Browser. Which I always keep installed with Signal.
