The thing is that not all servers in datacenters are maxed out to 100% usage all the time. A low priority process using idle resources could be used allowing for huge total cpu-power (given the scale of goog/fb/amzn datacenters) at no additional cost while if an agency wants $5B worth datacenter an agency must buy a $5B datacenter. On the other hand those idle resources could be rented to an agency at a discount price
