The problem now is information overload. Effectively we've gone from less information, to good information, to too much information causing overload leading to less information. This makes it easy for bubbles to form by various biases.
You can't just take information away or try to "curate" the information seen, that's what censorship is.
We just need to learn to live in a world where everyone knows too much about others and where it can be difficult to tell the difference between truth and lie.
