Very idealistic. Google started out with "Don't do evil", maybe they still don't but hell will freeze over before Google's data will be publicly available. Once OpenAI (LP) will grow, the stakes will grow and at some point it will no longer be feasible to completely release their results due to financial pressure. No charter will stop that. Not that I know of an alternative. It's clear they will not reach their goal without more resources, so the choice really is to pick the best of poor solutions... Personally I feel the ends don't justify the means in general, so I am somewhat disappointed by this development.
