I suspect you have misinterpreted the meaning (a-ha :P ) of the word "negative", here. It was not (I claim) used to imply "pessimistic, depressing, upsetting", but rather - literally - to mean "an answer which is 'no, null, empty, not-a-thing'". I'll freely admit that I didn't read to the _end_ of the article - but I got about halfway through, and I didn't detect any sense of disappointment from the author regarding their "negative" answer (nor, conversely, a yearning for a "positive" answer).
