For fun points, this is pretty much exactly what happened to Denethor. His phone (palantír) showed him vitally important information on very real threats, but also kept him in contact with misery and pain and malicious people who wanted to drive him into despair, and in the end, on top of tragedies in his own life, caused him to destroy himself (and nearly his family too).
So yeah. Be careful not to become Denethor?
And it also showed him nothing but the doom (the way both news sites and the majority of organic human information-sharing patterns do) even though there were lots of reasons for hope.
In short, Tolkien’s timeless message is: beware of Mount Doomscrolling.
