You are speaking a bit hyperbolically and that is not what anyone
believes or feels.
Much like any large datacenter or hosting provider it is not feasible
to police every packet in and out of the network, I assume "The World"
has lots of experience with super-scale networks so I'll limit my
"lecturing" on the subject.
Regardless, like any large datacenter or hosting provider they can
only respond to complaints when they get them, and they do, and they
respond (unless you have evidence to suggest the contrary). As a
corollary to this I was simply noting that their terms do not include
the ability to SMTP at all and as such the ranges are left in any
blacklists they might fall into. You are also free to block them for
SMTP on your own kit given this directive. Blocking at RCPT time or
even before limits any bandwidth usage from spam to negligible amounts
in most cases.
The consequences of blocking TCP/25 as an upstream though is much
worse since customers frown on upstream port filtering and it makes
SMTP impossible for everything except those which accept the
submission port. Many people may still have numerous valid reasons for
using port 25 to talk to their own kit somewhere else.
