This is dumb, and gives both IGN and Kotaku more power & attention than they deserve. Sony doesn't care about appeasing outlets that would just move the goalposts to something else to dog the game. Shift Up definitely doesn't care about these types of Western media, especially one who's on the verge of bankruptcy (Kotaku).
Frankly I'm tired of entertainment being used as tools in a (highly American-led) culture war of stupid. I'll just say the folks who want to boycott the game now because of small changes like the 'Hard R' thing or a bunny suit being slightly changed, were probably not genuinely interested in the game to begin with. And they aren't that different from the woke people who boycotted Harry Potter Hogwart's Legacy simply because J.K owns the IP (but had zero direct involvement with that game).
In fact, boycotting over that small a change would just be giving Kotaku, IGN, ResetERA etc. a W and, very likely, even less games remotely like Stellar Blade. So just think about that.
