Yes, the big advantage of duplicity when I first started using it long ago was that it used public key encryption, so the remote backup was encrypted but couldn't be decrypted without information not present on the being-backed-up machine. I thought that was a pretty fine idea. And that property is now broken.
I was sort of assuming the issue would be dealt with in the fullness of time, and in the meantime at least I'd have backups, even if I needed to open up a private key during the backup process which seems like a pretty bad idea. Of course, the shorter this window of not-properly-using-asymmetric-encryption is open the happier I'll be.
