> Well, they don't need to spend money to schedule my Lambda, but they did already spend a bunch of money building out the datacenter so they can pick up my 100th of a nickel when they do schedule it.

A projected revenue drop is not the same as a loss though. You already bought that computer.

Less so if it's your own company who was using their stuff.

Worst case scenario: they have stuff idling and more headroom to accommodate demand.

Heck, why waste more money building yet another data center if the ones already in place have already plenty of cycles rand bandwidth to spare?

It's all an accounting trick. You don't waste more power. You don't have to but more hardware. Turning off your lambda saves nothing.
