Setting aside the personal responsibility angle for the moment (which I agree with you on!) don't you think that negative externalities should generally be managed?
YouTube is a paperclip maximizer (where paperclips correspond to eyeball-hours spent watching YouTube) and at some point optimizing paperclips becomes orthogonal to human existence, and then anticorrelated with it.
I think it's a perfectly fair thing to say that maybe the negatives outweigh the positives at the present.
(This argument doesn't apply solely to YouTube, of course)
I generally agree with you, but I think YouTube being safe for kids became their problem when they launched a version specifically for kids and marketed it as safe.
