I think you're greatly misrepresenting the story. The reason why one would want products that are identical to official ones (from a technical standpoint), is because they will perform better (compared to a traditional knock-off). Looking at the reddit post where the evidence for this story seems to be compiled [0], it would seem that he does exactly that. He purchases batteries from factories that over-manufacture (or were no longer under contract to make) official Apple parts. He asked them before shipping to remove/sharpie over the logo, in order to prevent them from being considered counterfeit. He was angry that Apple was able to have Customs seize products which did not belong to them and were not stolen from them (apparently this technique did not work a few times).

I definitely think that he may not have told the whole truth, but greedy sleaze-bag liar is not how he comes out in this story (at least for me).
