      Vulnerability researchers find vulnerabilities. All non-trivial software has bugs. It's okay to pretend that's not true if it makes you sleep better at night, but it's not our responsibility to protect you from reality.

      Tautologies and scorn won't change the fact that this tweet contains significantly more information than just "bugs exist" prior to a release being fixed. And all this for those sweet, sweet, useless Internet points.

      I suppose it's useless if you're committed to helplessness. For the rest of us, knowing software is imperfect helps us build resilient systems. Clicking update doesn't make software perfectly secure, even if your vendor tells you it does.

      I see @matthew_d_green comment on toxic behavior in infosec regularly. Given this branch of the conversation, I do wonder how much of this is bad faith and how much is people not trying to engage with what has been said and "answering" things they imagine might have been said.

      Shouting "irresponsible!" at vulnerability researchers, then saying anyone who calls you out on it is "toxic" is bad behavior.

      It's also not common knowledge the ways that things are discovered, disclosed, triaged, fixed, reported to the media and to laypeople. Viewing any aspect of that process can look scary and threatening without the proper context. :)

      I had actively lurked full-disclosure for the better part of a decade; I would argue that there is some baseline awareness of the scene. Anyway, if @taviso wants to talk about what, specifically, I see as toxic we can hop onto IRC. RichiH on all the usual networks.

      Funny how it's always the ones with credentials like "lurked on a list" who can't wait to techplain disclosure to those of us actually doing the research 😂

          Only thing that's irresponsible is claiming RCE without getting code exec (this is a generalization; we'll see about this case)

          What’s irresponsible, is to expect the researchers who are already helping you voluntarily, to further work days for free, just to prove it on your own terms that you have a problem

          The very phrase “responsible disclosure” is a canard which tends to shame researchers. I prefer “coordinated disclosure”.
