As a data point, I stopped using it 10 years ago because I noticed I'd maxed out all the content for the language I was studying at the time without being able to actually, you know, speak or understand the language very well. Since then, all my friends who brag about their 1000 days streaks still can't speak those languages either. I think it's just gamified language learning that heavily emphasizes the gamification part at the expense of the learning part.
