I already said it in another thread but bears repeating. I believe unironically that Poppy's Playtime is one of the most cynical indie games ever made, everything about it is designed around not only riding FNaF's coattails and to pander to the clickbait youtubers that make a dozen of overly long spretentious lore videos (*cough* MatPat *cough*) and the typical reaction comps to "spooky" setpieces, plus the easily marketable characters to make sellable physical merchandise.
They wanted the huge payoff of the thing they were copying, but didn’t want to put in the effort to get that payoff naturally, causing the experience to feel hollow and derivative. They wanted the commercial success that FNaF had, leading them to build a commercial empire of what is essentially a tutorial.
