I'm automatically itchy when people talk about "ethical disclosure". If you truly do believe that people who become aware of vulnerabilities are ethically obligated to disclose them, setting terms on how they do that seems hard to defend. "Ethical" or "responsible disclosure" seem more like coercive rhetorical devices to get unpaid researchers to adopt the values and priorities of vendors than anything else --- that's part of the reason the term "responsible disclosure" has fallen out of fashion (it's been replaced with "coordinated disclosure", which is value-neutral).
