If I was sharing code and the response I got was "you should dot your i's and cross your t's" instead of "thanks for providing functional code for free" it would make me reconsider sharing more in the future.
Meh. I'm sure his comment was well-intentioned: If you spend most of your time communicating with computers then your communication with humans can sometimes tend toward the 'abrupt', after this long in the industry I'm pretty used to it.
The honestly, maybe you just shouldn't be so sensitive. The suggestions made were not harsh or insulting. If this kind of gentle feedback is so hurtful, then not sharing code is probably the right choice for you.
Part of the assumption demanded by and centrally beneficial to HN, is that we are adults here and can approach critical review looking for its constructive nature and well-meaning aspects. HN has greatly benefited from countless individuals, both commentors and recipients, being willing to see or assume that such comments are not personal.
(As one other reply has put it, "constructive criticism".
In this case, the great-grandparent is free to reflect upon the g.p response, or not, depending upon their inclination and time. Perhaps it sparks further refinement; perhaps not. But I don't see it as being personally critical; to reiterate, it offers a perspective of possible refinement.
In the past some months, I've noticed the tone of comments on HN becoming more "emotional". That, I believe, is a slippery slope for the community. HN seems to function best when we all exercise emotional restraint, along with our technical and professional enthusiasm.
With regard, and hopefully not "calling out" the parent too much (or at all) in what I have taken primarily as an opportunity to make a more general comment.
