This is literally Cartoon Network when it comes to treating their movies in terms of preservation. the ones based on the modern shows get to be on multiple home media stuff: DVD, iTunes/Apple TV, Amazon Prime, and Hulu.
While the ones based on the classic shows sadly only have scarcities, which means they don't get to be preserved multiple times in terms of home media or TV broadcasts the U.S., not even being on digital platforms (except for Ed, Edd n Eddy's Big Picture Show because it was always meant on iTunes/Apple TV).
