This community has had a long standing tradition of crediting a shape mod to the creater of the shape mod and not the original puzzle. For reference see the Fisher Cube and Trajber's Octahedron. So it gets confusing at times when puzzles like this come along. Is it something that should be credited to whomever made the new shape mod? Is it something that should be credited to whomever made the original puzzle? Or both? Is it a KO? Is it an original new puzzle?
Although these recent Chinese puzzles are often referred to as shape mods in reality of course they are not and I personally wish we would avoid calling them that. They are copied mechanisms with a new shape. A true shape mod actually modifies an existing purchased puzzle and therefore wouldn't be classified as KO since the mechanism designer has gained profit from when the modder purchased his puzzle (unless it's a mod of a KO of course).
My personal view is that a kind of hierarchy exists. As you probably know I have previously made and sold a rhombic dodecahedral (Gear Change) version of Oskar's Gear Cube. If someone copied and sold these I wouldn't be hugely happy. That is, unless it was Oskar or had Oskar's backing. He completely out ranks me regarding the mechanism and I would never dream of objecting.
So to answer your question, overall ownership is Oskar's. A modder of a legit puzzle with Oskar's mechanism (Gear Cube for example) would have a second level of ownership. A puzzle that copied Oskar's mechanism is a full KO. A copy of mod of a legit puzzle with Oskar's mechanism (Gear Cube for example) would also be a KO unless it had Oskar's backing.
I hope that clears things up.
BTW this is how I see it. I am not quoting any official policy.
