Stripe CEO here. I just wanted to let everyone know that I'm taking a look at what happened here. OP (disappointeddev), if you could drop me an email, that'd be great: patrick@stripe.com.
The last time Patrick posted his email[1] soliciting feedback, I emailed him but never got a response. I'm sure being a CEO is a busy job, so I understand. And I'm sure he'll respond to OP. But keep in mind just because he posts his email publicly doesn't mean he's actually any more reachable for it. [1]: https://news.ycombinator.com/item?id=9646672
(Two of us from Stripe, myself included, have already been in contact with disappointeddev.)
