It points to a pathology of HN that someone discussing their experience with a specific technology is getting downvoted and flagged for describing their own experiences.
He was shadowbanned because of his previous trollicious comment, not the one below, so your assumptions here are incorrect. Perhaps the mods are a bit quick to shadowban (or the algos they use are) - I personally think it should be reserved for persistent trolls, but have some sympathy - moderating a community like this is a hard, thankless task and there is an endless supply of toxic trolls. I'm sure if he asks nicely they'd reinstate the account.
