An act performed before an audience of millions is in no way private.

It is if only viewed by consenting adults in non-public places.

If someone stole a private videotape of yours and broadcast it on the internet, the principle would become clear to you.

The internet is not a private place. This example would be more akin to playing porn on a billboard in times square.

Internet sites are very rarely broadcast in Times Square, as far as I know.
