You're right, my bad: Wikipedia only mentions them in the "animation" section of the side panel, while the actual article only mentions Frederator and Powerhouse.
My reply was incorrect, and I'm not trying to move the goalposts, but it has to be said that the studios you listed have animated many of what would be considered "western" shows: Ben 10, Spiderman, and Animaniacs show up in the credits for Mua Film and Tiger Animation.
My intent was not to focus on the American aspect as much as the "this is very much a western production, unlike what Netflix is trying to imply." I should have worded it better.
