This just isn't true. Duolingo's mission is 'to make education free, fun, and accessible to all'. And for the most part they have succeeded at(or are striving towards) doing those things and have left the learning part to you. Maybe it is not working out for you, and that is likely the case for many people, but to say that their model is to create an unsuccessful learning environment sounds a little bitter.
