Multi-platform messaging app WhatsApp has announced a new option that essentially allows group chat admins to create one-way broadcast channels, a feature seen on other social services like Telegram and Discord … On the surface it’s a way for the Facebook-owned WhatsApp to give group admins more control, but it’s also a big step towards letting users turn the app into a way of receiving announcements or breaking news … Facebook’s social platforms have a reputation for borrowing features from rivals — like Instagram copying Stories from Snapchat — and it may be easy to see WhatsApp doing the same from Telegram, the latter is far from the only one to use one-way broadcast channels.
