What are you talking about. You think service providers can backdoor aes-gcm? There will always be technology that they cannot get around. The only way to backdoor is to explicitly change the encryption.
This is not specific to 'backdooring aes-gcm implementations' at all. Read again what I wrote, namely this is the general status quo on 'information system security': they don't need your password or aes-gcm key to watch if they really want to. You would be a fool to presume anything else.
