Dr. Craig has now been issued a fully vetted certificate of copyright by US Government Copyright office.
This can not be contested unless you have standing so this is now firm.
Dr. Craig has not applied today, he did that months back.
It doesn't matter. Anyone else can have the same copyright registered as well. Disputes over copyright ownership are sorted out in the courts, not the Copyright Office.
The whitepaper and original code were already copyrighted by default when they were published. Initial distribution under the MIT license destroys any chance Craig Wright has of charging rent to use the Bitcoin code, as he apparently intends to do.
It almost seems like another pathetic attempt to "prove" he's Satoshi more than anything else.
