I wish we could operate on the principle of data sharing in science. What a waste of resources to needlessly replicate and compete. Also, great, somebody else is doing it so we don’t have to! Less work for us.
This is already how astronomy, and specifically cosmology, research works in the US (and most other places). Data is made public within a short period of obtaining it on a schedule (usually less than a couple years) that is set before data is taken.
It is far from clear that the Chinese government supports this type of open data sharing.
