Once installed their app, Facebook thinks they own our mobile devices.
At first, there was the peaceful all-purpose Facebook app. And some time later they separated messaging into another app, creating the Messenger. Initially it was at user’s discretion to use Messenger or Facebook app for messaging. Initially it looked polite but lately everyone was gradually forced to install Messenger. Another app… sigh! Personally, for me messaging is just messaging. I don’t want a childlike fairyland for just sending and receiving messages.
