>I don't understand how end-to-end encryption protects illegal file sharers if the file ownership information is stored unencrypted.
It doesn't. Who said it was supposed to?
In theory it protects Mega from the argument that they know what the data is and aren't stopping it, because now they can't know, but YouTube isn't encrypted and nobody expects for them to be shut down, so I'm not sure to what extent that is really even necessary.
