Of course when you are using any service, you must agree on their rules. If you don't, then you must leave. I didn't agree on Twitter or Facebook rules or behavior, so I recently leave their service.

But that doesn't allow you to publish any video which infringes any copyright, neither on Twitter, Facebook, YouTube, LBRY or publising a link into the Steem blockchain. Law protects rights, wherever their property is published.
