OP here. Unfortunately this thread is mostly misinformation. There were a bunch of viral threads from the growth hacker / influencer crowd, including this one, within hours of the code release with a very superficial understanding of the code (and how recsys work in general). That's partly what motivated me to write this article.
See here for a rebuttal of the main tweet in that thread (near the bottom of the article). https://solomonmg.github.io/post/twitter-the-algorithm/
