I've seen people share passwords, secret keys, and bunch of other sensitive info in corporate Slack (ie. treat it the same as they'd treat eg GMail or Google Docs on a corp account). If Slack wakes up one day and starts feeding that into a generative AI that has the potential to regurgitate it wholesale, "nightmare" doesn't begin to describe it. And after the first incident, I imagine there'd be a flood of companies dumping Slack for anything else.
