They didn't care about Yasuke because they are used to crazy historical retellings like Samurai Warriors and Sengoku BASARA. Also, Koei has had him in a bunch of games long before Ass Creed used him for diversity points. They even had him both in serious war simulation games and in bishoujo gacha games where he is turned into a brown loli.

The only way I can see them caring is because it's a western made game so they'd have all the rights to be wary. But Yasuke himself is not different from what they are used to.
