Now the European Union recently announced a rule in the Digital Markets Act (DMA) to require messaging app developers to enable their apps to interoperate – that is, to make them work together. For example, if I’m a WhatsApp user, my message might be received by an iMessage user, if that user does not use WhatsApp. Additionally, if I’m an Android user with RCS, my message could be received by a Telegram user or even an iMessage user. There could be endless combinations.
… to read the various headlines such as from BBC, or FierceContent, (and quite a few more — not all of them, mind you, but quite a few) you might get the idea that here is something that will be the true “SMS killer.” Notwithstanding the over-imaginative headlines, I think Facebook Messenger is nothing more than an expansion of the popular online-based Facebook “chat” service. I would suspect that this is more of a threat to various Instant Messaging (IM) services than it is to SMS. The problem with IM is that the various communities have never really been interoperable with one another (which makes for good business for products such as Trillian by Cerulean Studios – users may sign into multiple IM communities using a single client or app).
