Ignoring scaling issues, I don't see how they could compete with radio, in terms of informational and artistic value. If their premise is that radio is simply content read out loud, then that is a vast underestimation of the polish and narrative structure that radio producers add to a broadcast.
Most radio anchors ARE qualified to be professional voice actors. But a great radio report is not just great writing, but a different form of writing.
