It doesnāt matter what you think might happen. What BlockShareholders decide to do with their own dev funds is completely up to them. If they do receive the dev funds back, then I donāt seen any reason why they would need to be sent to another DAO.
B&C will continue being B&C, but have the money to finish development and Augeas will most likely end up being a replacement for Nu. If B&C doesnāt get the funds back, then the network may end up getting abandoned by shareholders like Nu.
