Buuut... Just because you made a good business move and hedged one of your raw materials, doesn't mean your competitors did. If your competitors didn't, then you might as well rise prices and just take the extra as profit.
Or... look at it another way, you bought some nice energy futures contracts when they were cheap. You might earn more selling those energy futures contracts now they're very valuable than you make putting that energy into servers and selling the compute.
What is "loss leader"? Do you mean they make a loss on EC2, or that it's the bottom entry if you'd sort by profit? I'd assume the former but making a loss at AWS' price level would be extremely impressive.
