That sounds like you're putting (some of) the blame on whoever misclicked. As opposed to everyone who has allowed this insanely dangerous situation to exist.
This. The person that erased the database in my case came forward to me as soon as we realized what had happened. At that moment I was very happy it was an "inside job", it meant I could discard hacking.
As its said before: he made a mistake. The error was allowing the prod database to to be port forwarded from a non prod environment. As head of eng that was MY error. So I owned to it and we changed policies.
