My initial comment wasn't clear. My point was - there are tens of thousands of open, unanswered cases there. But it's only a handful of distinct categories. Meaning cases can be programmatically categorized, and handled by Support employees in batches. I've done tech support before, and you can make a small team very effective with some organization and good automation.

Also, don't underestimate an importance of a ticket update (any update). If you observe a few open cases on Reddit or Twitter, you will see that the worst thing you can do is say nothing - no ETA, not even an acknowledgement... it's the complete silence that makes people freak out and open multiple cases, spam multiple channels, only aggravating the problem.
