It's because humans are motivated primarily by fear, not logic.

The exact same moral panic was made about fuckin printed books. This is all hysteria, just like the TV is evil phase everyone went through. Proof of this is that nobody can even agree what social media is, let alone point to what's actually harmful about it

And we have even worse examples: it's depressing to see how many people "don't believe" in the principle of vaccination. One may be tempted to say "people don't have the time to become experts in every topic", but when you look at the energy people put into sharing their beliefs around those topics... clearly they would have the time to read a bit.
