I hope nobody really believes Snapchat DRM is going to prevent their nudes appearing on a porn site. Just take a photo of the screen with another phone. If any

  One valid threat model for revenge porn is, I trust this person now, but if we break up I might not trust them anymore. So Snapchat disappearing messages do actually solve that problem. (And more generally, "I trust this entity now but they might become compromised in the future" is a model with some precedent in encryption, cf. forward secrecy and deniable messages which are for related, similar problems.) It's also not unreasonable to hold that the additional effort of taking a photo of the screen falls into the locks-keep-honest-people-honest category. Of course nobody believes that a lock on their front door will prevent a sufficiently determined attacker from breaking in, yet we all lock our doors. (And we wouldn't say that "change the locks" is useless advice against an ex with a key.)

    No they don't. Taking a picture or screenshot of such an image immortalizes it. Stopping people from taking screenshots is essentially rootkit or virus functionality. (Plus it doesn't stop anyone from taking a picture of the screen.) You're trusting the person to not make this image permanent. Could be valid, could be a serious problem. That's if they just don't make the revenge porn out of slightly enhanced deepfake cloth.
