Interesting history and analysis of SMTP's history. How can we prevent fedi and other open protocols from suffering the same fates?

You're spot on, and even smaller ISPs routinely get blocked by larger hosters (anyone who doubts this, please look around for the many stories along the lines of "gmail silently drops my email")

Residential IP blocks are scored much higher and given a negative trust from the start - not surprising since that's where much of the world's spam comes from through compromised computers, routers etc.
