I wonder what relation there is between a Stack Exchange website's meta and SO meta. If the admins of Stack Exchange website X say in their meta something that contradicts some posts on SO meta, what should I respect when posting in X?
For example, these posts (1, 2) on SO meta say it is OK to copy answers into technically different questions. However, this post on Cross Validated meta say it is not OK.
I don't want to enter into this specific argument, but I'm curious to know what rule prevails when posting on the Stack Exchange website whose meta overrode some SO meta rule (Cross Validated in this example).
