In many ways it still is - it requires too many permissions and the list is growing. Recently they're asking for access to my SMS messages and in Android 4.3 I had a bug with my Nexus 4 in regards to location services as the Wifi-network provider was draining my battery and so I had to disable it, so Facebook's app was still requiring it, activating the GPS on each opening of the app and there was no way to turn that off, unless I turned the GPS off globally. Granted this is also a failure of Android's permissions system, but ...
The mobile web interface was and is still there. It doesn't matter if the mobile platform is new or old, it doesn't matter if Facebook's app was developed (and approved) for that platform, the web interface is there and it works, the only requirement being for the user to have a decent JS-enabled browser.
People view Facebook's investment in their mobile web interface as a failure. I view it as competitive advantage.
