I reckon the negative reactions are at least partly down to your wording, e.g.
> there is no good work
> total lack of discipline
> impossible to build
This level of absolutism is problematic for a couple of reasons. Firstly it's ambiguous: a "total" lack of discipline would entail never releasing anything. This is clearly inaccurate, and the reader is left guessing what level of discipline is implied. Secondly, without more detail, most will assume exaggeration, given that RoR sees significant commercial use. You haven't provided compelling reasons to trust your judgement over anyone else's, so users are well-justified in raising counter-examples from their experience.
You also come off as dismissive of opinions and lived experiences that differ from your own; suggesting that anyone who disagrees is a "devotee", and that concrete counter-examples are meaningless one-offs. Having been on the sharp end of this dismissiveness myself, it mostly acts to drag the discussion down. Like, fair enough, maybe you're incredibly experienced, you want to make the world a better place by passing on your wisdom, and you're tired of dealing with half-baked takes. But belittling your fellow users is not helping. And again, from my own experience, you can be quick to say that a take is half-baked even when it aligns with scholarly opinion.
