I think it's the wording that's being commented on. Maybe it's just semantics. I think the word 'disappointed' implies that there was an honest effort that didn't end up panning out (say, if the company ran out of money, or misunderstood product/market fit and fizzled, or got out-competed). I am not sure what a more appropriate phrasing would be for a fantastical idea that never existed in any form and never could have.
