The headline is a lie, but the other part - Goldman did not steal open source, because what is being given for free can not be stolen. (Moreover, if they didn't redistribute the code (which I assume they didn't, based on the article), they didn't break the OS licence either.)
"Goldman Sachs Steals Open Source, Jails Coder"
Which is a lie.
It depresses me that even HackerNews upvotes headlines they know are untrue, if it suits the cultural narrative.
