"If Fazbear Entertainment wasn't sold at all, they just sold their pizzeria(which is Fnaf 2 location) to another people, but didn't sold the entire company to another people, that's illegal to use Foxy as their animatronic mascot, because that's property of Fazbear Entertainment" well, this variant of lore fixes this issues because this people bought Fazbear Entertainment, that is, they bought an ENTIRE company, and now they have right to use Foxy as their another animatronic in the pizzeria(that's screenshot from introductory cutscene from FNaW: Unreal Engine 4 edition by the way)
