Um, why is it Google's fault that some random blacklist erroneously
listed some of their IPs?
As someone else said, it only makes sense to block IPs if you believe
they will never, ever send mail your users want.
That's not how blocklists work. They lists IPs that are sources of spam.
Mailservers get compromised. Client accounts get phished or hijacked by
spammers and used for a spam run. Spammers sign up with freemail
providers and send spam.
Blocklists absolutely should list these as spam sources, because they
are in fact spam sources. And when the spam problem is fixed, they
should delist them.
