The quote explicitly states that this is per quarter. Let's say "tens of millions" means 30 millions. So that's 10 million per month. If there are 500 people that's an average cost of 20K/month per person. I assume many people will have much lower salary but I also assume there will be infrastructure costs.

Can you clarify how it's hyperbole? Did you read it as being a yearly cost despite the quote referring to it as quarterly?
