> Is your app as large and important as the OS of the device (Chrome/facebook/etc...) you should probably have similar language across devices.

No app is more important than the OS, and certainly not Facebook (which has no business being an app in the first place). I made a choice when I got the OS, and I like developers respecting it and not chase the fad of the day with poor approximations of the native widgets (text fields that do not support standard shortcuts, buttons that do not behave as they should, labels that do not support accessibility features, the list could go on). Even huge apps like Photoshop or Office get this wrong everywhere.

I definitely agree on the default (use the native toolkit), but there are no applications big enough to get their own behaviour. Open Source or hobby applications get a pass if the UI is a bit wonky, but that’s about it.
