Your solution to admin incompetence is for a centralized service to eliminate the admin. Why can't the service just provide competence? If dozens are people are working round the clock to eliminate spam for your free mail service, why can't they package that and let you control your own data?
The centralized solution you've proposed carried to it's fullest extent is basically eliminating email altogether, where a small cabal of whitelisted services are only able to pass messages to each other. If spam detection software must remain secretive and proprietary at these big companies, this is basically a capitulation to the spammers.
