Be aware that this post has known issues that the author is not interested in fixing. In their own words (in response to clarifications by one of the OMEMO folk):

"I'll make an edit later about the protocol version thing, but I'm not interested in having questions answered. My entire horse in this race is for evangelists to f** off and leave me alone. That's it. That's all I want." [censorship of profanity mine]

You won't find this quote in the article with Ctrl+F, it's in the screenshot, where they omitted the original constructive comment by one of the OMEMO contributors that they chose to moderate, which you can find here: https://www.moparisthebest.com/tim-henkes-omemo-response.txt

So, by all means, read the blog post. But just be aware that its ultimate goal was not to be an unbiased accurate technical article.

Oh I can't get enough those blog posts written in such confident language that it's easy to filter them out instead of having to realize midway reading how wrong every bold claim they put forward is… :þ
