I'm very interested in this discussion
Technically they didn't post his content there... They referenced his post, simply shared a link in the post. We looked up that link and showed the post and correctly attributed and forced the user to give their post rewards to the original author. So is this comparable to someone is saying they don't want their content talked about or seen by another group of people?
Is this like saying the NY Post doesn't want their news article linked by Trump on twitter because donald trump supporters will read their news and that's not who they want to cater to with their public news article.
Yes, it is an interesting aspect.
What is possible however is to edit the post after CPing, and make it look like something it is not perhaps. Yes, the history to the edit is there, but there is also the potential for taking payment on something that wasn't the original.
I have seen some users CPing and then editing in the original post to make it look like a new post. it does make it look nicer, however it also takes away the "warning" that this is a cross post and therefore anther instance. THey are doing this on their own posts of course...
