Adsense "users" are actually business partners with google. You share revenue, pool resources, etc. In my mind, that arrangement should encourage a higher level of service than most customers.

I'm saying that the poor service offered Adsense partners isn't excused because they're not customers. If anything, it indicates that customer service will be worse based on this totally made up hierarchy that I've just made up (partners more important than customers, should have higher priority service).
