Whether or not it is fair for it to be on you, it still is. Because it is your problem whether or not Medium succeeds, not ours. Even if you are 100% correct, and HN's attitude is completely incorrect and unfair... that don't hurt us none. It does hurt you. (If you care about us as a potential market segment.)

So it is on you because you are the one who needs the brand to be viewed positively.

Specifically, it is on you to put on a product hat, come understand what we feel, why we feel it, and what might make us more interested in your product. Or not. Your company, your choice.
