Hint: 'Personalized' algorithms simply mean tailored to one's biases. As in Google will show liberals only liberal articles, and conservatives conservative articles.
I think there's an important distinction between recommendation algorithms, which is how I'd describe what you're referring to, and _algorithms designed to maximise engagement_.
Recommendation algorithms try to provide content that you'll enjoy, like new movies to watch.
Engagement algorithms will try to find content that keeps you engaged, even if that means enraging you. They don't just exploit biases, rather they exploit what triggers you.
