It's also confusion that reporting of a bug is not criticism. It's a Show HN. You've asked for the feedback. People that get twisted when the feedback is anything other than pablum like "great job" need not be a developer. If you can't handle being told that something isn't working, then how do you ever expect to improve? Or maybe you've moved from being a dev and are now trying to be a founder?
I think that is a feature, not a bug.
