Culturally Open
As can be seen, some of the Culturally Open nations have Nation Descriptions, but these are only advisory and are not enforced. Bear in mind that some of the Culturally Open nations which were once Culturally Protected are linked to old Cultural Protocol bills, but this does mean those Cultural Protocol bills are in force. It it simply that the previous Cultural Protocol bill has been treated as the Nation Description.
For more information on the process by which Culturally Open nations can adopt, change or remove Nation Descriptions, please see the OP to the Nation descriptions in the Cultural Protocols Index thread.
