Some commenters here appear to be using "harm" in the psychological sense, with the implication being that spending time on social media is damaging to a child's mental health. If we accept the premise that spending time on social media is bad, then a modern algorithmic feed is probably more-bad than a boomer board.

To be fair, the article itself opens by citing both the mental health allegations as well as "exploitation and abuse". Given we're dealing with an emotionally charged political hot button issue, it's safe to say these are intentionally muddy waters.
