Does matrix even support end-to-end encryption? Last I checked it didn't have /any/, except maybe server-to-server and even that wasn't enabled.
I also seem to remember going over their homebrewed cryptographic rachet and it didn't properly HMAC.
EDIT: Apparently riot.im supports E2E, but it's not a part of the Matrix protocol and it's not encrypted by default. The Olm rachet was also audited by NCC, so that's nice.
