Even worse, there is no proven connection between the spam and the

entirely consistent with spammers using lists of verified email

That would be make sense only if the number of hotmail/yahoo spam
sender addresses were proportional to the number of hotmail/yahoo
addresses among all targets of spam.
I disagree. You're assuming that the spammers will distribute the
'from' addresses evenly among email addresses they have. I see no
reason why that's true. I used to receive waves of bounces &
notifications about spam allegedly "from" my domain. I did *not*
receive a steady trickly of such bounces.
Unless you think that most spam targets are at free providers, you
must assume that spammers have some reason for prefering to send as
if from free providers.
Spammers do it, therefore they believe it's useful. Our ignorance
as to *why* they believe it's useful isn't an argument disproving
their behaviour.
