That's a huge number of people in absolute terms, but a tiny minority when you're investing heavily in a localisation and courting the media across several continents. I think character-wise the single thing I've been less than thrilled about is Matsu's changed Basara, but she has actual R2 moves now, so I ain't even that mad. In short, they're wary of the negativity that would follow a major company using a crowdfunding site to fund a localisation indie gamers and publishers alike would condemn the 'abuse' of the system, and the press would spread rumours that Japanese companies were planning to use this method to avoid localising other games properly in future. I just do not think enemies that can't be hitstunned are fun to fight, period.
