Nginx was built with 'single server' architecture in mind while Google generally operates on a 'distributed everything' architecture. This involves stuff like distributed file systems/data stores. My guess is it's not compatible with the single file system interfaces of Nginx. Also note that dl.google.com serves stuff on a massively bigger scale than the majority of the rest of the internet. On that scale I'd guess they face some rather uncommon challenges and bottlenecks that can only be addressed by custom software.
True, but a static-file server should be trivially scalable. That is, scalable by placing it behind a load balancer(or using any number of alternative methods that don't acutally touch the server itself).
Even if the server implements Access Control, it should still be trivially scalable.
I mean, if by "rather uncommon challenges" you're referring to the "what are threads?" design philosophy of the original... then yeah, it does require "custom software".

Also, nginx doesn't have such...interesting ideas as the custom server: http://talks.golang.org/2013/oscon-dl.slide#19
