like sword and shield are pretty explicit about the fact that dynamax pokémon usually, er, go on rampages and the whole “using them in battle” thing was something chairman rose, the big bad guy of the entire game, invented to increase spectacle, which was opposed for probably ethical reasons by the person who was most knowledgable regarding the dynamax phenomenon, professor magnolia
