I hate such an approach when someone assumes that whatever happens their opinion is the best one in the world and everyone else is wrong.
I do not want to encrypt my backups because I know what I am doing and I have very, very good reasons for that.
Restic could allow a --do-not-encrypt switch and backup by default.
The arrogance of the devs is astonishing and this si why I will not use Restic and i regret it very much because this is a very good backup solution.
Try Borg.
