I don't know, it's one way to do things. You're signing up for an experience like this. Hopefully you're aware of that. If you're not, and you find you dislike the experience, you can stop without any significant loss.

It would be interesting to see multiple user experiences that you can choose between. If you find gamification motivating, you can choose that. If you just want a list of lessons and exercises with no artificial progressions, you can choose that as well. That would be an interesting next step for UI design to take, seeing as many of our objections to an offering are UI based. If companies can capitalize on that fact, they can cater to a larger user base, and alienate fewer people.
