I'm the author of the linked post and I didn't use ChatGPT or other tools, not even a spell checker. But I'm not a native English speaker and my writing may come across quite differently.

Given the author's sentiment at the end of the article I'd say that's unlikely, but even if it was that's kind of irrelevant to the point at hand.
