My thoughts are this: even at 100x, the service credit is probably not that significant to the recipient. But the amount at 100x is significant to Slack. As the recipient, I don’t think too much about the money I receive back, but I know those credits in aggregate are quite painful to Slack (and a lot more painful than they could have otherwise justified) so I know they are taking the issue seriously and will work hard to prevent future outages, which is worth a lot more to me than the service credit.
