IMO duolingo is aimed at peopple(adults) who say they want to learn a language but aren't ready to take it seriously
In US/Japan etc. the largest age-group of learners is 13-22

Any sort of LLM-based tutor is tricky with children as you can't guarantee that it won't come up with something inappropriate, even with the various guardrails in place. As a parent, I'm happy to take that risk especially if I am around to explain anything, but if I were a teacher for example then I probably wouldn't be and I imagine businesses are going to be in a similar situation.
Same.
For over a year before I finally gave up on it, I was force-quitting the app and reopening it for the next lesson because that was faster.
You know, like Yamaha with pianos, power amps, motorcycles, outboard motors ...
The thing here is that you have nothing that you can patent that Duo Lingo would have to buy from you, if you're just putting a skin on someone's AI.
Only theoretically; in practice, Duolingo have a specific brand — IMO aimed at helping younger kids with schoolwork — they don't want to risk damaging, so if you target your language course at people who chafe at the style of art, animation, voice, and/or content of Duolingo[0], you still have a business opportunity even though Duolingo is also already working with GPT-4.
