SMTP blocks, when most of what's on EC2 doesnt actually originate
email?   Access to it would be over http which isnt firewalled.  Or
maybe ssh gets firewalled off.

Death by a thousand access lists. Ouch.

This simply means there must be a lot more effort - from their
upstreams, and from their peers (not in a "network sense" as much as
"large network operators who are of a sufficient size to talk to
amazon and ensure that they're heard".   To convince them that some
filtering at their end, and implementation of abuse handling best
practices would be a good idea.
