A possible partial answer is at http://ccnpitdaddy.wordpress.com/2009/03/20/smtp-blocked-outbound-esmtptls-fix-asapix/ - some Cisco equipment does this by default.  So the question may have no meaning as applied to the ISP - they may not even know how it works.  There is the question of why Cisco would make such an option the default.  Are customers asking for it?  Or was there no real conscious decision made - it's on by default because that's the way it happened to come out in the code and no one complained.
