Many, many companies claim to be doing what they do for the good of all humanity - they would have you believe that any profit made is just a nice side effect.

Examples:

* Aon insurance - At Aon, we exist to shape decisions for the better — to protect and enrich the lives of people around the world.

* Nike - Bring inspiration and innovation to every athlete in the world

* Glencore - Responsibly sourcing the commodities that advance everyday life

I don't really see any difference with OpenAI, beyond their name including some fluffy sounding loveliness.
