so in one of the cutscenes, specifically the one before night 5, it explains how something that doesn't wish to be forgotten grows angry and given a second life

this is obviously talking about Freddy's, which was left abandoned presumably after the rumors of murder, and the aggressive animatronics not hesitating to kill anyone within it's way

but with Ralph coming in clutch and posting screenshotted images of the characters in the cameras on his blog, it's given a positive effect

everyone starts to remember what Freddy's is now, shown by messages of people sharing Ralph's blog everywhere, and this nostalgia starts to calm down the animatronics and finally given the attention they deserve

that's why the place is "quiet here now", the animatronics are now put to rest, knowing they hold a special place in the hearts of children before demolition happens

thanks to @ShadyStorkGames for making a great fnaf fangame, let's hope there will be a(n easier) Freddy's Reanimated 2
