Fox have tons of pg-13/g movies and tv shows - the Blue Sky films, Percy Jackson, Home Alone, Maze Runner, Diary of a Wimpy Kid, The Martian, Cast Away, Devil Wears Prada, etc... Aliens/Predator are like what 1% of Fox catalogue. The Simpsons and Avatar are already heading to Disney+. The Nat Geo shows would probably show up as those are educational shows and for all ages. Also before Comcast decided to sell Hulu, Disney already got 60% of Hulu. An asset is an asset.
