GoktimusPrime said it quite well in a previous post (unable to find it though) that the cost of reverse engineering a toy would be significantly higher for HasTak as they have different production standards when compared to your average bootlegger. These would include marketing, quality control, registering trademarks for names in some cases etc. Bootleggers don't seem to care about legalities as the product they are making is technically illegal significantly reducing the cost of producing KO toys.
