What metadata has yet to and can be encrypted? The recipient, the send time and the message size seem impossible to encrypt.
I think the better question is, "What could count as metadata that we don't have to encrypt?"
But to answer yours: https://github.com/vuvuzela/vuvuzela
Encrypting metadata is a huge challenge. In the meantime, our best bet is to use open-source systems that we know won't be harvesting metadata.
I hope the public soon realizes that harvesting metadata is just as valuable to advertisers as the actual content of your messages. In fact, it's arguably more valuable since you can discern all of the details without any of the regulations.
E2E Encryption is ad tech's latest sleight-of-hand. Everything, including the metadata, should be encrypted. It's otherwise pointless.
