Unfortunately this is inaccurate. There are billions of daily adolescent YouTube users, some of whom entering puberty that were exposed and continue to be exposed to the recommendation algorithm that created this mess in the first place, and for periods running into hours every evening.
At such an early stage in development, it is absolutely the company's duty of care to ensure that a 5 year old is not being sent up a gradient of a recommendation system that is encouraging them (with the help of the comments just removed) to view people of their own age in a sexual manner. Not only were children impacted by this, but the mechanism that enables it remains active to this day.
I agree with the idea of allowing children outside, but as per my reply to your previous comment, not if that means spending all day in the back yard of the village creepy old man. Balance is required in every situation, and denial of the kind your comment is riddled with accomplishes nothing.
