I do agree with a lot of what you write. I maintain that Duolingo is the wrong approach to actually learn a language (even though there are differences between the various languages covered by Duolingo). However, I did somewhat successfully use Duolingo to refresh some intermediate-level Italian grammar (not grammar training, but I could observe various grammatically different sentences), after having been away from the language for fifteen years. This was some twelve years ago, and Duolingo has changed so much for the last few years (mostly for the worse, while I was still wasting time on Duo for for another language), so I don't know the state of the Italian course now.
