Well of course, but we all know Facebook isn't a responsible company and Apple shouldn't assume that every app in its store is made by a responsible company.
They're currently in court arguing about how they make users safer by curating the available software. Issues like this don't reflect well on that argument.
They could fix the problem regardless of whether the app was downloaded from the app store, a third party store, or just sideloaded, so I don't see what you're getting at.
