Claim is pretty straightforward. Mohan blames viewers and takes no accountability for any extremism on YouTube, repeatedly failing to acknowledge the role of autoplay.
This paragraph summarizes it nicely:
"Even the reporter interviewing Mohan seemed surprised, at one point interrrupting him to clarify, “Sorry, can I just interrupt you there for a second? Just let me be clear: You’re saying that there is no rabbit hole effect on YouTube?” (The “rabbit hole effect” is when the recommendation system gradually recommends videos that are more and more extreme). In response, Mohan blamed users and still failed to give a straightforward answer."
