Let's look at access to research like access to healthcare.
I hope there won't be many dissenters if I posit an increase in GDP resulting from a healthy populace.
I'm not just talking about outsiders being admitted to the community. I'm saying that information as an ecology has resources that if opened to the community, could provide insights that are unlikely to happen in the current situation. So access is a generally healthy thing, but access for all will be unpredictable in terms of productivity.
Federating all data, irrespective of scale will happen in the near future. Denying access is something I wouldn't want to be remembered for.
