I'd say the higher you move up in management, the more and more your own goals should represent the business's goals. A lot of ICs don't really care about the business, however, and I think this is where promotions are used as a tool to get them to care.

If you act in the interests of the business, the leadership of a company will (usually, but not always) reward you for your service to the business. Whether or not this is something you "should" do is up to you, in my opinion. As an IC, you can't make me care about a business. I'm there to get paid and gain career experience, the latter of which sometimes improves the business and sometimes not.
