> For actual businesses like Linkedin though, it makes more sense than not to unsubscribe from unwanted emails anytime they're sent.
Why? What's in it for you?
You filter them = never see the spam they send you again
You unsubscribe = pray that it's not a phishing email disguised as linkedin spam, hope that if it's real they don't just start sending you different spam, and that maybe they haven't agreed to sell your (now confirmed as more valuable) email address to 3rd parties (aka, their "partners") now that you've made that email address worthless to them otherwise.
The absolute most you can ever hope for in the "unsubscribe" case has the exact same outcome as the "filter" case, while the filter case has less risk and as a bonus lets the spammers waste their time.
