The title states “Masahiro Sakurai refused to add Dolby Surround to a Kirby game because players had to sit through the logo” presumably because you actually cannot have Dolby sound without the logo. Yes, technically you could, but it’s likely part of the license agreement and so him refusing to display the logo as outlined by the license means he couldn’t use Dolby sound in the game (or would get sued if he went ahead and did it anyway).
Nope. It’s just an unnecessary label which provides no additional features, i.e. no benefits. You can have Dolby sound without the Dolby label.
