I’m not sure if they’re concerned with Saturo Shibata directly, it’s just that under Reggie, Nintendo of America pushed hard for stuff like free Wii Sports and cheaper prices (which worked great, making the Wii a huge success), while the Nintendo Japan was of the opinion that nothing should ever be given away for free.

Under Bowser, Nintendo of America fell in line behind Japan. Culminating in stuff like the welcome tour for the Nintendo Switch 2, something that us just a tech demo of the device you just spent $400+ on, costing $10.

Having Saturo Shibata as CEO, it seems this will get worse, not better, since Nintendo Japan is excerting more control over NoA.
