(from the last "shower"):

I'm guessing their servers are 100k each? No basis for that guess though.

Seems strange to make the guess without basis then says so.. except that it's suspiciously in the right OOM. Perhaps it was unconsciously based on that "shower" article providing a cost estimate for AWS, as well as an estimate of the premium over hardware.
