> WhatsApp - WhatsApp feature means some encrypted messages could be read by third party. > Alternatives: > Signal - Uses Signal Protocol. Pretty sure both WhatsApp and Signal both use the Signal's crypto for encryption, and both "suffer" from the same "design defect" / "usability improvement". That said, I still think WhatsApp only encrypts text messages E2E, and doesn't bother for videos/photos/anything else, based on how efficiently it forwards videos compares to sending them for the first time (accounting for video conversion time), so I'd still put WhatsApp in the bad list, but not for that reason. Being owned by Facebook is enough of a good reason in itself at this point too, mind. EDIT: Just read through the full list. This is superb. Thank you for putting this together! EDIT AGAIN: Just read through some of the comments, Iridium in particular is what got my attention as awesome, prior to learning that it's not been updated in 5 months, which is beyond dangerous given the number of security fixes that will have come out in that timeframe. Sad times :-(
