Great. Pretty sure jen20 did too; they are replying to a comment pointing out the article is wrong and suggesting a compromise between the web default "enter all your address, then the zipcode" and the article's "you don't ever need to touch the country, state, or city fields" that is closer to working beyond the US. In that context, I find it strange and rude that you're suggesting they didn't read the article.
You also suggested I hadn’t read it. “I won't violate the site guidelines by suggesting you didn't read it”. Only you did (saying you won’t say something and then saying it doesn’t really absolve you).
I find you rude so I won’t reply to you anymore.
They were pointing your own faulty claim back at you, in the hope that you would reconsider it.
You should not be treating it as a standalone accusation, and it's not justified for you to get mad at them without getting just as mad at yourself.
