The damage is that if you're writing about cryptocurrency as a topic, the same way any media publication would (rather than trying to scam anyone or sell anything) you're still getting shut down.

I think this is way too broad and leads to absurd conclusions. For instance there's an MIT research group whose mailing list I subscribe to (not mailchimp) and which would fall under marketing by your criteria. Papers with specific cryptocurrency names occasionally appear in top CS conferences.
It is very difficult to find non-marketing content in modern times. Especially in America.
Like, if you want to have an erudite discussion of the technical and mathematical underpinnings of zk-SNARKs, there must be a substantial number of people in that discussion who are capable of setting up a Mailman server.
Here's a response from MailChimp to a nonprofit educational org that suggests they are willing to make distinctions and not just class everyone who writes blockchain-related content as shady: https://twitter.com/MailChimp/status/981554164626010112
It seems you're saying that MailChimp should be entirely neutral and should let you promote anything you want, and they disagree. MailChimp does not want to allow cryptocurrency promotions. Cryptocurrency promotions have negative externalities. That's not collateral damage, it's the entire point of their decision.
Whether they are "equivalent to ICO scammers" doesn't enter into it.
