Just for some perspective, if you want to know how little reach the fedi post with the link to this blog post got: the first post in this thread already has more likes and boosts after less than a hour since posting it than my blog post ever did that he felt the need to confront me over.
The author probably wasn't aware that their blog post has a huge engagement in hacker news just the day before and the CEO got roasted there, so the CEO probably felt the need to contact the author to "correct" their post.
