I had a look at the website and it looked fine, not my tastes (I like mono fonts), but overall perfectly acceptable.
Perhaps a discussion about the content of the article would be more relevant.
I don’t think there is no reason. The reason is a bad font that most of us have hard time to read. It literally catches the eye and discourages to read tfa.
I think it’s all because of that macos fonts quirk.
If I was posting the article for myself, I would be quite disheartened to spend so many hours and get such direct feedback.
I think its better to leave balanced comment and some positives or not to respond at all. I read the comments and thought to myself oh boy have to check out this site, it must be terrible, which I hardly found to be the case.
