I'm not sure why every "Show HN" post attracts somebody that points out that what OP has created isn't novel. It's a big world and novelty isn't half as important as quality of execution and UX.

The purpose of these posts isn't to lay focus on what's already out there, but to focus on what OP has created, usually for the primary purpose of critical feedback so they can improve themselves and their product.

Part of critical feedback is comparing something to its competitors. Of course, the GP could have done a better job at this.

That would be perfectly valid criticism. If they'd said "there's x and y competitors and they do [...] really well - might be something you'd want to look at because these are very heavily used features", that'd be really constructive feedback. But all noodly said was "theres already one" and solicited contributors.
