If they don't notice the dropped subscription, I'd say they're not 
negatively impacted.

And, if they contact IETF to find out why the subscription was dropped, 
IETF should have a mechanism (such as an email address external to their 
blocked IP) by which they can communicate with such people and remediate 
the issue.

You're not the end recipient. I assume you have out-of-band methods of 
contacting customers that were blocking you (such as, say, a phone 
number). Yep, more work for you as a sender; still not impacting on the 
end recipient.
