I don't think he is saying that encrypted communication should be illegal. He's saying that spreading lies through encrypted channels should be stopped. It would not be hard for WhatsApp to prevent people from spreading bogus videos, because they have access to the unencrypted information before and after sending. So either preventing people from sharing misinformation or preventing people from reading the misinformation. That's separate from the argument about whether or not it's a good thing (I wouldn't see a problem with it personally).
