> Firstly, it refuses to provide a data backup mechanism for iOS/iPadOS. If someone loses their devices, there is no way to restore older messages.

This is not the only case where Signal has decided that users should not be in control of their own data. For example an Apple Store or authorised repair shop may need to reset the phone, or an OS upgrade goes badly and needs a restore will also lead to data loss even if there is a full local encrypted backup made.

It is really orthogonal to the much of what Signal claims to stand for them to so boneheadedly insist that users should not be allowed to own and control their own data.
