Product updates, offers, and security newsletters

Whats the point of this in the preferences if it does nothing:

() Email me product updates, offers, and security newsletters
We will continue to send you information relating to your orders, account updates, Automatic Renewal service and important security alerts regardless of this setting.

I still get the product updates, offers, and security newsletters emails no matter what. Perhaps norton feels all there emails are important security alerts?

Only thing I care about getting from norton is if my information was taken or my system was hacked. otherwise I do not need your excess ads about new products. Hence the unclick of this item.
