The real story here is that now we know what Osmeta, the stealth startup Facebook acquired a few years ago, has been up to. Look inside the installation directory for the Messenger app, and you&#x27;ll find that it&#x27;s using an iOS compatibility layer. Unfortunately, that&#x27;s bad news in terms of accessibility for blind users, at least in its current form; this thing isn&#x27;t firing any focus events. But I&#x27;m sure that can be fixed.<p>Edit: I referred to the Messenger app, but the same applies to the Facebook app. The Messenger app was just the one I looked at first.
