Nintendo is historically HUGE on being family-friendly and controlling their image. Streamers telling raunchy jokes, dressing sexily and/or swearing while playing a Mario game probably does hurt Nintendo's brand, at least in their eyes. There's a reason Smash Brothers Ultimate's online mode only has voice chat in private rooms through a smartphone app.
