That's normal behavior when your server is being reverse-engineered or abused. Video bandwidth is not free.
Apple's decision is not constrained by server logic or ballooning costs, it is entirely a client-based policy to not sign CUDA drivers.
There hasn't been any abuse in this story as far as I know, it's not like mass downloads of videos happened with their client.

Microsoft rewrote their Windows Phone native client to pass through Google's ads. Google still blocked it.
Was it normal behavior when Google blocked Amazon Fire devices from connecting to YouTube with a web browser during the Google/Amazon corporate spat?
To be fair, Google did back down almost immediately when the tech press picked up on it.
Not allowing a native client for your monopoly market share video service on Amazon devices while also blocking Amazon's web browser on those devices is making things a bit too obvious.
