That's not the point of the analogy (some other siblings got it wrong, too, so the fault is likely mine). The point is that it's inherently very risky for you to contact someone about a problem they created accidentally, negligently or possibly intentionally in order to get it fixed (and that might result in them being fined or otherwise punished when the issue becomes known). So you should not do that. You should either seek a trustworthy intermediary for you to handle the interaction (this might be difficult / non-existent in your locale) or reveal the issues anonymously.

Again, it's not about Optimally Mitigating Corporate Security Fuckups, it's much more basic than that: it's about keeping you safe. This should obviously be priority #1. Anyone telling anyone else to do responsible disclosure by default because That's What Good Guys Do And You're Not A Good Guy If You Don't is quite clearly not putting the safety of the reporter at #1.
