Non Playable Characters (NPC) are not a new thing.
In 1887 Josh Billings published
"Edukashun iz a good thing generally, but most pholks eddukate their prejudices."
In 1906 Bishop William Fitzjames Oldham was recorded as saying:
"People assume they are thinking when they are merely rearranging their prejudices."
Theodore Sturgeon published a story It Wasn't Syzygy which was written in 1948 where he explored the concept that most "people" are stage props and present as 'real' because they reflect the light generated by the very few who can function as fully human, much as the moon appears luminous because it reflects the sun.
Even more recently the noun "tool" has been ubiquitous in popular entertainment
Just sayin' that NPCs are a part of the human condition and censoring people who point them out is to deny part of what makes us human.
