A reasoning cited in the article is that there was no source control in place for the trade tooling that Goldman Sachs finance employees were building.

I'm guessing that + probably the absence of any deployment infrastructure for the finance people to be forced to use made Goldman Sachs' eyes widen and pull the plug immediately before something blows up (if it hasn't already internally).

I also wonder if a lack of diligence with Claude Code (or any LLM tool for that matter) resulted in private information getting leaked, and that feedback is just now getting back to them.
