It seems like the point is, you can see the same issue in very different ways. Did you read it from the bottom to the top? I was cringing until I got to the end and found the message to “Now read it bottom to top”. Still not saying it belongs in a technical document but it felt way less abrasive after reading it both directions.
The spicy bit is that this is the first release that contained such a political message. And also the first one that is managed by the guy who started the mess of this post, too! Not exactly sure if he's the one who put it in there, but it's one heck of a coincidence.
