This is an example of a KO trying to pass as a Fan kit:

The toy is not adding anything to an existing toy nor creating a new unique toy in the likeness of Hasbro's intellectual property. It's blatanly replicating HasTak's invested R&D into a scaled down unofficial toy which they are happy to sell and profit from without paying any royalties to the company that went through the procedure of creating the design.
It's not trying to trick anybody that its official but it is benefiting from the design and development of another. It's almost 100% Plagiarizing the engineering and design of a toy made by another company.
To me this is more in the realm of theft than any third party accessory kit or custom parts. I would indeed call this toy a KO.
