I would like to recall my own Three Laws of Co-Creation.
Law 1 states that any for-profit company that uses closed proprietary content, and excludes participation, will tend to loose from competing for-benefit institutions that can count on a community of voluntary contributors and uses open proprietary formats.
Law 2 states that, when two for-profit companies are competing, the one opting for open and participatory strategies will outcompete those who do not adopt such practices.
Law 3 states that communities of peer producers which successfully can ally themselves with an ecology of business practicing benefit-sharing with the commons they are deriving value from, will be more successful that those that remain isolated.
