How would you verify e2e encryption on a proprietary protocol? Not every company that cares about privacy has crypto experts on staff. They should have a reasonable expectation that the vendor is telling the truth.

1. Is the software proprietary? Liability, Denied.

You can't. Don't trust, but verify. If a company or individual needs strong privacy, they should verify any encryption claims.

This would mean using only libre/open source software like Jitsu or Linphone, as one could verify the code or higher experts to verify the code.
