I have criticized omemo in the past -- it breaks backwards compatibility way too readily resulting in XMPP clients not being able to talk to each other in levels that I hadn't seen since the Jingle debacles. However I just can't stand this article's tone (the accompanying imagery doesn't help), and then he has the balls to complain about the rude response he gets from the spec authors (even showing it off as if to elicit empathy from the reader), when if anything my impression is that his article itself is way more disrespectful.
He keeps criticizing one client while trying to pass it off as criticism of the specification (said client doesn't even implement the latest version of the specification, either), complains about the protocol changing too much and the protocol changing too little, and to top it off seems to promote Signal as the better alternative, completely missing the elephant in the room -- Signal being centralized with its decisions even more whimsical at the hands of one group only. Curiously, he does that right after criticizing omemo's choice to follow Signal's choices as lacking justification.
