Right, but even when offering free resources to the public you still maintain the manner in which they are accessed and distributed.

It's not as clear as let's say access to a public park on private land. But the idea would carry weight that youtube may control the manner in which their publicaly accessable website may be accessed.

Let's say you can access via the YouTube app which does not require an account, and now you reverse engineer that app to bypass the app all together. It's a bit like cutting a hole in the fence around the playground.

I'm not a fan of what happened it's just clear to me why it happened.
