Maybe companies will lean more on in-house solutions as code getting cheaper, building their own walled ecosystem. Fine-tunning their internal based on their findings. Keeping all the knowledge for themselves.
On the contrary, I think groups that adopt a share-alike approach will, counterintuitively, deepen their moat by increasing the amount of effective world-history-knowledge reflected in their systems. I thikn this will be true for the same reason that conditional-cooperation as a strategy is the optimal one in most iterated Prisoner's Dilemma games.
