The real question is whether they'd have used it to begin with— I’d guess not. It seems most folks here discouraged by streak-loss had sizable steaks to lose. That means they reaped real benefit and provided real revenue for duolingo. Nobody uses a language learning app forever.

The gamification requires two coordinating motivations— secondarily the game mechanics, and primarily learning a language. Duolingo won't replace candy crush for non-language-learners. I imagine folks significantly discouraged by poor game performance without doing some serious learning first just aren’t motivated enough to practice their language skills in an app.

Personally, I’m not motivated by gamification at all and am content to ignore it. It is noisy, however, and I also wouldn’t mind the ability to shut it off.
