As I understand it, the idea is that it's a "sandbox" or "test" network. Confidentiality implies a "production" use case, and HAM doesn't want to be the venue for those. You can play around with encryption if the keys are public but you can't actually keep secrets. Even if the secrets are non-commercial. It's a place to play with radios, not a personal communications network.
