But security researchers don't exist in a vacuum: they're part of larger society. If the security researcher subgroup has a code of ethics that diverges too far from the popular perception of what their code of ethics should be, I could see popular pressure to bring them into alignment (all the way up to using the legal system).
I'm not saying the non-security researcher users on HN have an opinion representative of the public as a whole, but this comment and a previous question asking another user what security research they've published may point to such an ethics disconnect between security researchers and the broader populace -- or simply a disregard for the concerns of the broader populace. I think it would be beneficial for security researchers (or any professional group) to listen to ethics concerns of the broader group they're a part of.
On another note, I would also assert that abusive actions by vendors do not excuse abusive actions by researchers (and vice-versa).
