The incident is clear cut and makes RubyCentral staff look incompetent. They cut off access to 1password and did not even consider that someone may have a copy of the credentials somewhere? As in "maybe in their head"? Rotating shared credentials in such a situation is security 101 and they failed. And when Andre notifies them that they failed, instead of quietly saying "Thanks, we've fixed that", they make it a security incident and include - without any further context - a single email from something that must have been a longer conversation.
My current read is that RC majorly botched the takeover, demonstrated gaps in security know-how, and then retroactively framed everything as a problem with André. The details of the logs are mostly immaterial to the rest of the claims, but are still suspicious enough to spice up the announcement. I believe this because, at the moment, I don't see anything in the original RC post that wasn't satisfactorily explained by this post.
