The amount of vitriol here is amazing.
Yes, they should have posted about it here first. However, whoever posted it to the social media may have been reading the delay as only a couple hours and not a full-blown scrub for the day.
I can understand the extra care taken with this one, as it directly ties in with payment systems. As such, any small bug there could result in a massive headache to the tune of costing thousands of dollars in chargebacks, man hours, processing fees, etc. I'm not saying this is the case, but had this been released and the issue was something that allowed a rogue agent to illegally conduct transactions using your payment information, one of the top complaints would be that it was released too soon.
Chillax guys.
