From that link you should also be able to find conversations on Hacker News and the like. It was talked in a lot of places at the time.

If I’m remembering correctly (take this paragraph as imperfect memory), at the time a lot of people on the outside were looking to assign blame but the team tweeted something to the effect of “yes, we know who did it, and no, they won’t be fired” and didn’t even reveal who it was. Then they live-streamed the process of trying to recover as much as they could. They got a ton of community encouragement and it was widely viewed as the right way to handle things.
