You don't have just one company wide chat channel - when I used chats and came to the same conclusion as the article. It was a large company and we had hundreds of group chats. So the C++ Embedded developers and Ruby would be have separate chat channels. ALso in that case you still put out your question without the details and the relevant people will be able to answer others can ignore it, but sometimes it does help for a different expert to see the issue and ask for clarification and then come up with a new solution.

As for repeating to external - I don't see that as a problem - well it fixes itself quickly the leaker would get fired pretty quickly.
