It's just that people have different understanding of the world and assuming something is self evident is dangerous. For instance the problem here is the apparent disconnection between the comment and the article, but maybe it's just that the connection isn't evident to you.

Take this response to a comment of mine for instance https://news.ycombinator.com/item?id=48144461. I've read the article and someone thought I didn't because he didn't see the connection I saw and acted all righteously, almost as this threads OP.

So in order to avoid embarrassing yourself online it's always nice to first give people the benefit of the doubt and then avoid being sneaky and clever when communication what you want.
