Notifications about the change are going out to some users in Europe starting today, and they’ll have about two weeks and see multiple alerts before the requirement to download Messenger kicks in. Eventually, all Facebook users will get migrated to this new protocol. And you can bet some users are going to be angry.
When asked for comment, Facebook referred to Zuckerberg's comment on the matter back in November:
“the other thing that we’re doing with Messenger is making it so once you have the standalone Messenger app, we are actually taking messaging out of the main Facebook app. And the reason why we’re doing that is we found that having it as a second-class thing inside the Facebook app makes it so there’s more friction to replying to messages, so we would rather have people be using a more focused experience for that.”
How do you feel about the change? Do you use the main Facebook app for messaging?
You can download Facebook Messenger from the App Store for free.
