The ads on duolingo make it super obnoxious to use and I wouldn't be surprised if people dropped their attempt at language learning for that reason alone. I mean, if the options they face are dealing with the ads, paying an annual/monthly fee to not see them, or quit then a not insignificant number of people are going to quit and that sucks. I wish there were a free and open source alternative. I've got a 20 day streak tho, so clearly the ads aren't bothering me too much, I'm just annoyed.
