It's interesting that in the post there's a maintainer pointing out that there's a very tiny little checkbox that says "this will process X PB of data". Given that your account knows how much your queries cost per TB it does seem like an "dark UI" design to not just say how much the query will actually cost.

Similarly that checkbox being a tiny part of the UI, and not allowing people to set up cost limits on a query (or not having them at the account level), does seem very much like an "encourage people to overspend" UX. I'm sure "overspend to the level of a $14k bill to an individual" is not intended, but that's a reasonably predictable occasional outcome for this design.

So on the one hand, yes they did click a checkbox saying they were aware of the amount of data being processed, but OTOH the UI seems to be specifically designed to encourage this kind of mistake.
