Right.

Sheesh, we went through this a decade ago.  Approximately none of AOL or 
Yahoo's mail users pay for the service -- they're the product, not the 
customer.  I know a fair number of people with AOL accounts, they're not 
super thrilled about AOL, but the cost of switching and telling all of 
their correspondents is huge.

It is abundantly clear that Ericsson and AOL and Yahoo do not object to 
their users sending mail through discussion lists.  Ericsson doesn't want 
their execs to be phished, AOLhoo doesn't want complaints "why am I 
getting spam from people I know."  In each case we know from experience 
that their published p=reject doesn't describe their actual policy.
