For a variety of reasons, I'm a great believer in CBT as treatment for mental disease.  And it's not just a matter of 'belief' - imaging technology developed in the 2000s actually shows brains 'rewiring' themselves when CBT is successful.

Unfortunately, the real issue is that many people are in fact too depressed to believe in or follow through with CBT, which requires the individual's commitment to making the changes to thought patterns and beliefs about themselves.  So I'm not sure how, without support, this online approach might work for these kinds of people.  But perhaps it's a leg up in another way - they don't have to show up for group meetings and work with therapists who they don't feel comfortable with.  Interesting to see where this will go.
