it's basically what seems like the official SNH48 Weibo replying to a fan, complaining about the copyright fee, how the price is insane, and how even though they paid the copyright fee, they didn't have access to the storage of songs that AKB owned.
Also brought up an interesting point, the reason why KFC was a promotional MV was cause when they said they're going to use KFC, AKS said that would be copyright infringement.
Honestly, it looks legit, but I personally think this was fabricated, because I don't see the official Weibo talking badly about JPN48 like a smart idea, especially since they mentioned how much some of the fees costed.
But who knows, maybe the company is stupid enough to reply like that. Everyone's human, right
