Unless they are changing their support process to not require a user to post on a message board and hope a developer sees it, I don't see how it's really taking responsibility.

And why should I give them more leeway for outsourcing to an inexperienced company? Comma/decimals meaning in currency is pretty well-established. If a new company is moving into an established space I would expect them to learn from other folks past experiences. "whoopsy, we don't know our core competency" isn't a defense for a company that's presumably making exorbitant amounts of money from partnering with Anthropic.
