You could call it bias, or you could call it alternative motive. Several key third parties do not want Nintendo to be the platform of choice for hardware, because they do not want to compete against their software. EA is in this category. A few, like Take-Two, seem to have a mild bias and just prefer to work on other platforms. There are bias in favor of Nintendo too, like Shin'en for example, developers that grew up with Nintendo products and dreamed of making products for them. Other companies, like Ubisoft or Activision just want to make money and will put games on Nintendo platforms if it makes sense, but sometimes promote other versions because they were given money to do so.
But bias definitely exists.
