We were in no way one of "their biggest accounts". We were a couple guys in a cramped office over a mattress store, with a production service so small we could have run it from my old laptop. I guarantee it cost them at least 10x more to send those consultants over to us than we spent on AWS in a year, even before the optimizations they pointed out.
Yes it is, but the gp is also right that it is part of a well calculated and proven way of keep existing customers and getting new ones. $$$ is the reason they do that, else this would not exist.
