Without discounting social media's harmful effects:

I do think Instagram in particular has been a boon for small businesses, providing them visibility in the marketplace that was previously unavailable to them.

Social media has also been a way for communities to connect organically with discoverability features missing on the old web.

There are positives and negatives - if it was only negatives people would be quicker to abandon the platforms.

Although I'm not familiar with the case at hand, I agree there's potential there for real harm, especially to children.
