To be fair to the original commenter I believe they were making a Mean Girls (2004) reference. The line in question is "Stop trying to make fetch happen. It's not going to happen.". Likely just a funny quip and nothing serious :)
Besides, it wouldn't hurt HN to loosen up a little once in a while. You know, obsessive total adherence to rules is never a good thing - even to the law.
But it’s just low effort, extremely online snark.
