Even in the scope of the original comment, doesn't it create a pretty perverse incentive to allow companies to mark HackerOne bugs as WONTFIX and then ban researchers who disclose them?
Isn't security through obscurity largely to be avoided? I thought the working model for most security researchers was: if it's not worth fixing, it's not worth hiding.
More to the point, I thought that responsible disclosure always came with an expectation of public disclosure. The advice I've always been given is that you should never disclose with conditions -- ie. "fix this and I won't tell anyone."
It should always be, "I am going to tell everyone, but I'm telling you first so you can push a fix before I do."
