It's not that weird. Disney is an 800lb media gorilla. When they rip something off it's punching down. I am a poorish dude in a bedroom when I rip off Disney I'm punching up.

Which is why I don't give a shit about Disney ripping of kimba in this case. Tezuka is/was a media giant in Japan and the Lion King didn't really do anything to harm the Kimba IP financially anyway.
