It wouldn't surprise me if that was a standing order from the top - make sure it can scale to everyone on the planet. I built a service not too long ago where they were expecting 50M users in the first year. Real numbers? It's hovering around 300k users. But the good news is it can handle those 50M if they ever come :-) It is highly over-engineered.
