I don't know why you'd think I'd be surprised that MailChimp has customers who use it for its purpose, which is marketing.

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.
