One of Reddit's main pressure points for forcing reopening was that it was "unfair for the users" to keep data hidden and inaccessible. Mirroring all that data takes away some of the leverage. So I can understand the value... we can move and we don't have to worry about Reddit taking its ball and going home or claiming it deserves to be hostile because it is the steward of so much information.
