That's neither true nor fair; downvotes are explained by the commenter clearly wanting to escalate the argument. collision said tends to, so the objection here is weak and certainly doesn't merit name-calling like "Laughable".

A better way to phrase something like this is as a question. For example: "Wouldn't these criteria apply to Shopify? If Shopify is a legitimate business, how can other legitimate businesses overcome the same hurdle?" Putting it that way would abide by the HN guidelines, would be more likely to get a substantive response, and would take the thread in a direction where we all learn something.

It's hard, of course, to keep one's poise in a discussion about one's business being rejected for an arguable reason, but the alternative is for people to yell at each other, which helps no one and degrades this site.
