The Pokémon Company has been self-conscious about their image since for ever. They were very nervous about releasing the 3DS Detective Pikachu game way before the movie was a thing. Masuda also stated he was unsure if a talking Pikachu would change Pikachu's image for ever. That is why they only approve these things if they are very well done, and they oversee the whole project like helicopter parents.
Sega on the other hand has been whoring Sonic for years. It's a joke of a character.
