Well, here's why:  Spammers use dialup, and other cheap lines, to bulk
email their trash directly to other mailservers.  So, if I run a
legitimate mailserver. I have to make a choice whether to accept email
from all of Comcast's IPs or just the ones identified as Comcast's mail
servers.  If Comcast blocked port 25 then Comcast becomes responsible
for approving their users behavior, etc., rather then EVERY other
business.

Your clients should use business solutions, not home solutions.  I know
of NO ISP that port blocks on business data lines.
