Disappearing messaging and media is popular. As with encryption, WhatsApp’s introduction of the feature will popularize it, with many millions of users likely to enable this new privacy protection. This is especially true given WhatsApp’s reported plans to offer a default disappearing message option for all your chats—rather than having to select individual chats to apply the setting.
Mark Zuckerberg has confirmed that WhatsApp’s view-once media is imminent, telling WABetaInfo earlier this month that “we're about to start rolling out view-once... which will make WhatsApp more private and secure.” Who wouldn’t want to disappear all the regrettable memes and photos and videos they’ve ever shared? Sadly, that can’t be done, but you’ll soon be able to stop the problem getting worse.
