There are numerous ways for collateral damage to be avoided when ISPs block port 25: For instance, users can use port 587 where appropriate, or ISPs cansimply whitelist users who request not to be blocked.
There's at least one consumer ISP who has said that given their levels of churn, *one* support call eliminates *all* margin for that account for the lifetime of that account.
One support call to whitelist against blocking means from at that point onwards one more call and you're costing them money rather than making them money.
