You mean the response that says, verbatim: "I'm thinking about the points that have been made, and I'm sure that we as a team will consider them going forward" ? Sure, he also says for now the behavior won't change, but that's the sane thing to do with the errors are rare, as changing something too quickly may introduce new bugs or unforeseen problems. Honestly, your interpretation of that comment is the exact reason why it's good to shut it down for a little while. The conversation gets so charged that even a "we need time to think about it" response is viewed negatively.
