Seems pretty clear from context they meant "financial" or perhaps "related to money", I don't think we have to put them on the spot for it.
I imagine this is part of the meta-point you're making across the thread that people on HN talk out of their hat about finance (I plead guilty) but I feel like your comment about Money Stuff/"truth searching" was enough, and that asking people to defend their misuse of terminology is punching down.
