David,

  These packets are not *to* 0.0.0.0; they just claim to be
*from* there.  Unless a router is specifically configured to
check the source address for validity, it won't care.  (The
RFC passage you quote prevents attempts to *reply* to such
packets from saturating the whole Internet.)

Agreed. Thank you for the correction. 

"..SHOULD NOT originate datagrams addressed to 0.0.0.0".

Use of the words "originate" and "to" in the same phrase to represent traffic 
flow seems, at first glance, to be in conflict with each other, and is likely 
the source of my misinterpretation.

Another example of the importance of semantics when then intention is to 
communicate accurately.
