I can't currently say that I am a compiler writer, since I'm working on static analysis tools, but I have been a compiler writer for more of my career than I have been anything else, and I was thoroughly amused by the tone of the paper. It's not particularly professional, and it's not likely to change minds among the people he is excoriating, but I don't think that's the point. Instead, I think he's trying to shift the "Overton window", to embolden people uncomfortable with the status quo, so that they can argue for what they want instead of accepting the opinions of compiler writers as some kind of unchangeable holy writ.
