Maybe I'm too pessimistic, I apologize if that's the case. But I fail to see how the company could ever work on "the right thing" "forever" since there is outside investment in the company. Do these investor not want a return on their investment at one point? If it's in 1 year or 10, eventually they are gonna want you to either go public, or get bought by another company, both of which makes the mission goal change from "the right thing" to "the profitable thing" at that moment.
But again, maybe I'm just overly pessimistic based on bad experiences with VC funded companies.
