The later, the parroting of facts and the inability to go into deep detail besides being told information tidbits and repeating them is what makes the NPC so chilling in todays world. Especially when a few people get that high level of norieity and trust.
It's kind of weird that this is attributed to 'memeculture', given that I can recall people referring to others (in a denigrating fashion) as NPCs back in the 90s, before 'meme' was part of our lexicon.
What you've discovered and described is called "NPC" by meme culture.
