No. "Disappearing" messages are a farce. Disabling other people's screenshot capability so someone can be made to believe that their message will disappear is absurd. If you want a message that disappears, tell them in person and pat them down for a wire. Also there's nothing wrong with simply screenshotting licensed content. I'm allowed to do so for my own personal use. If someone is distributing licensed content that they are not licensed to do so, that's a matter for the courts.
