Hasbro have said on quite a few occasions (usually at BotCon and the Q&A sessions) that Takara/Tomy is the only one dealing with the Factories. Hasbro has to go through Tomy like an agent to get their toys produced and then sent to America.
Different levels of "quality" or paint-apps are just designated by Tomy based on what they want and what Hasbro want off their separate production runs.
If Hasbro really is upset about this report, they would be chasing up Tomy first, to get them to investigate "their" factories, and/or attend to the situation.
