I thought it would be a good idea to centralize all NMA discussion about the hatred of newspapers. I think that Protagonist Man hates newspapers (as we see in the video) because of what happens between the prologue and the main game footage we saw in the E3 demo. Vault 111 was actually a horrible Vault-Tec/Enclave experiment to produce sentient newspapers that would take over the world after the apocalypse. Protagonist Man unwittingly leads his family into the hellish lair of these newspapers, which enslave for 200 years. Then, by way of a MacGuffin, Protagonist Man is freed from the newspapers and released into the wastes. When he meets Piper and she mentions newspapers, this mentioning invokes terrible memories of his centuries of servitude to the evil newspapers. That's why he hates them.
