What's wrong with it?

"Show HN is for something you've made that other people can play with. HN users can try it out, give you feedback, and ask questions in the thread."

Looks like you can try it out so not sure why do you think it's not good for ShowHN?

All you can do on that page is sign up. Sign-up pages are explicitely listed as a type of page that can't be a Show HN.

This sign-up page especially rubs me the wrong way as it uses a dark pattern: It grabs your email address first and then tells you that you cannot proceed without entering your credit card details.

I'll say that's more incompetence on my part than a "dark pattern". At this time you can only have 1 channel per account, and I need to check the email is unique before sending the info to Stripe, that's the way I came up to solve that, presenting that form before payment.

My product has not been used yet, just put it live yesterday. My idea here was just to get general feedback, like yours.
