There is a morally good and morally bad way to do this. Proton did it the right way. OpenAI is doing it the bad way.
The first paragraph on: https://proton.me/foundation
Proton was created to serve the world, and the non-profit Proton Foundation ensures that this can never change. As Proton’s primary shareholder, the foundation exercises its control to ensure that Proton does not deviate from our mission to build a better internet that serves the interests of all of society. Our legally binding purpose is to further the advancement of privacy, freedom, and democracy around the world.
In contrast, OpenAI seems to be leaving the nonprofit with a minority stake so watch it all collapse under corporate greed, or simply become worse, or squeezed dry after infinite growth investors get their hands on it.
