I actually don't understand why people try to separate this from NCL not only because both NOA and NOE started doing the exact same shit at the same time for some reason, but we also know that NCL likes to have a lot of control on its regional subsidiaries.
If we start hearing more and more issues about the Asia (South Korea, Hong-Kong, etc.) side, then it won't surely be only a problem with the Western staff.
And honestly, Gamazumi's Sakura Melody not even getting a Switch release in Japan is already a red flag for NCL
