Respectfully disagree. That may be one of the most non-Lubavitch things you could say.
I don't mean no hope as in they can't come back, as many do. But from the yeshiva friends I've seen, once those go, OTD quickly follows. It indicates a crisis of faith.
We had a similar discussion on DDF when Matisyahu shaved his beard on whether he would go full OTD.
Granted, all anecdotal.
