The trick is to get your egoistic interests to align with what is good for the world.

Environmentalists also only do what they perceive as doing good (and may as well be objectively good) because not doing so won't jive with their self-image. But that in itself doesn't devalue the thing they did.

If Valve shows anything it is that not being a pushover and trying to align your business interest with your values (and not vice-versa!) can also pay of economically.
