AWS Announces Executive Assurance Program, Prints $$$

Amazon just announced new premium support options.

My first reaction is sticker-shock. Monthly plans are calculated thus:

SilverPlan = (totalUsageCost * 0.1 > $100) ? totalUsageCost * 0.1 : $100

GoldPlan = (totalUsageCost * 0.2 > $400) ? totalUsageCost * 0.2 : $400

The 20% goes down to 15% and then 10% as your monthly costs increase on the gold plan.

I can see this being useful as FUD-defense, (and a warm cuddly blanket for nervous executives), but not sure if I can see anyone paying this tax if they are actually spending real money on AWS.

I welcome criticism if you think I'm reading this wrong...
