Spam is by definition messages that the recipient does not want to receive.
Whether or not the recipient wants an email is an orthogonal concern to whether Google promotes it. When Google places email in someone's Inbox, as opposed to Spam, Google is promoting that email.
That is not a spam issue, that is a censorship issue.
Alright, it's a censorship issue. Censorship on one side; genocide on the other. Ideology or pragmatism.
