You're correct, it is very reasonable for someone not remember details about a language that was used in schools for education decades ago, that he himself said he played with as a kid, as I have done myself. AGAIN it's not that he didn't remember, it's that anyone who has worked as a programmer for decades, and I mean without exception, would ever in any circumstance post that code from memory. Because anyone who has done any coding knows you only remember syntax when you have been practicing in it daily. No one remembers the syntax to BASIC, it isn't a useful language. You would just search for "hello world" loop and you would find endless examples you could copy pasta. Which he himself says he likes to do with that creative commons nonsense he tags to every post.
Sure pop-ups suck. Sure interface design needs to be better, it's not the point. The point is he claimed that the site was paywalled, he was wrong, that's okay. He was told by multiple people he was wrong, including one person who went as far as to post a screenshot. Even after all that effort from the community he doesn't just say "ah my mistake, I see it now", he goes into an excuse of bad UI design, even though no one else had the problem. It simple, just say you made a mistake without making excuses. Really easy to do, and way less effort than this whole deflection thing he does.
He's a shit poster, who bullshits people because he doesn't want to be wrong. I am under no illusion anything will change with this guy. His shitty behavior continues today just as it has in the past. I just made the mistake of saying something about it.
