Bkub is a good man and the shrieking hordes that assaulted him deserve the pillory.
He didn't apologize for their sake though, given he didn't make any comment when post #8206405 inspired similar responses. It was because Japanese users began responding to said comments too, forcing his hand lest he look bad to the companies he works with (Nintendo included).
So I skimmed through the bigger and earlier surviving quote tweet responses. Seems like Bkub apologized after about 12 hours and, if I've got the timeline correct, accidentally drew more attention to the controversy, thus dragging it out for at least another three more days. The whole thing's dumb, wouldn't recommend reading.
