I doubt this. People are willing to reupload videos that they like, so why wouldn't they seed? for example this video has been reuploaded quite a few times because people like it so much: https://www.youtube.com/watch?v=Mhu-EA1ruNk

The whole point of a video hosting service is to act as an easy directory for finding videos you like. The fact that the same service happens to host the videos in this case is inconsequential.

Reuploading is just a single shot upload of a few gigabytes.

Continual seeding to millions of peers is not.
