GP is partially right:

According to Reuters sources, Apple abandoned plans to offer iCloud backup encryption, out of fear of government retaliation or even spawning new anti-encryption legislation.

On the other hand, GP is responding to:

> Nobody who is at risk for this is doing iCloud backups. That's something you can already turn off.

And indeed, if you turn off iCloud backups, there is no "backdoor" into iMessage. You can also set up your phone to do encrypted backups locally to your laptop, if you want that instead.
