Coming back hours later, I'm going to be a bit harsher on myself: if I had checked the about page, I'd have still commented on the proofing errors, but I wouldn't have been so snarky about it, and I wish I hadn't been.
You're also right in your second paragraph, though -- the article didn't read to me like "this is someone who isn't fluent in English," it read like "this is someone who's fluent in English but tossed this article off quickly, made careless mistakes, and didn't bother to make a proofreading pass."
