The problem is what you're describing has more in common with Catholicism (particularly penances) than it does with Stoicism. The article is poorly argued. For instance, the article provides no real evidence that Dorsy gives a shit about Stoicism, and provides no real evidence that a few anecdotes of penance-like behavior is a trend, let alone has any causal link to a perceived trend of Stoicism.

Other HN commenters have suggested that the discrepancies between the behaviors described in the article and Stoicism are the result of techies corrupting Stoicism, but I think an alternative hypothesis should be considered: that the author has corrupted Stoicism in order to create a palatable narrative.
