Why do they need to?
Customers use their services anyway, and are either:
a) spammers, in which case they're happy that the above does not happen, or
b) non-spammers, in which case they don't really care whether their outbound
email is filtered, so long as it gets delivered.
In the (b) case, if there *were* filtering, any false positives (ie: legitimate
emails which got blocked) would harm the provider's reputation and customer
satisfaction.
Also in the (b) case, anyone who blocks email from the provider is "obviously"
causing the problem themselves, and therefore doing themselves harm.

How does that help? Those providers don't set up different IP addresses for
email from different customers. Everyone's email (spammers and non-spammers)
gets processed by the entire farm of outbound MTAs.

I doubt that is much of a concern for these size organisations.

Ha. I don't think their support staff extend to that level of assistance.

No. Email is a cheap service to provide alongside all the other services
they're charging their customers the real money for,

I suspect you don't have any of them as customers. Telling them to change
their mail service provider is simply going to tell them to use another
organisation instead of yours. If you block their email you clearly don't
want to do business with them.

Blocking IPs cannot work in a commercial environment (by which I mean, you
want to receive emails from legitimate enquireres for your commercial
services, or from existing customers).
