I'm not sure what you expect everyone involved in such a culture to do, but the same disregard from executives that caused a lack of documentation (and runbooks for software I was on call for) caused the overnight Slack shutdown.

My parent corp guaranteed no one would use it as a knowleldgebase by implementing a 30-day maximum retention period in Slack. (Same for Teams chats).

Lots of our staff got caught out when all the channels got truncated. Oof.

Not sure if that counts as a success or a failure. More like a failure because you learn after wasting a whole month. And then everybody has to learn the same lesson.

Success. It got everyone to stop using slack as a knowledge base.

It's like when sysadmins get confused when people use the recycle bin as storage and the user gets angry when the bin gets cleared.
