Facebook
Facebook currently owns and operates three messaging platforms that all run independently of each other - Facebook Messenger, WhatsApp and Instagram. All three platforms feature their own respective messaging component; Instagram users, for instance, can't use the app to contact users on WhatsApp.
WhatsApp is limiting its users from forwarding single messages no more than five times, in an attempt to stop the spread of fake news through the messaging platform. The service, which had allowed users to forward messages up to 20 times, announced the new policy in Jakarta, Indonesia where the country is holding its general elections.
BlackBerry Spark
BlackBerry has released an update to the BlackBerry Spark Communications Platform for developers. The biggest change to this release (R6) is that developers no longer have to manage their own Key Management Service (KMS). When you create your domain, you now have the option to have BlackBerry Manage and distribute your cryptographic keys.
