The general theme of the thread seems to be security industry people, like tptacek (or commenters self-identifying as being in the industry), expressing concern with the researcher's actions (while still admitting Facebook didn't handle it well). The primarily negative comments don't seem to have a specific affiliation tied to them. And given HN's demographic, odds are much more of them are developers than are infosec people.
I don't think the person you were replying to was suggesting that any infosec people who fully support the researcher aren't real infosec workers. I just don't think he saw any who even claimed to be.
