Please, yes, let him stop posting about Yuzuru Hanyu. Please.
He won't have to "put up with disrespectful fans" and in turn we will lose out on him writing about his private conversations with Yuzuru during his recovery when he told him about the light ahead after the dark times, and we'll miss out on lecturing the fans on privacy etc here and there because apparently tons of positivity is just not enough, when there're a few messy people, as there always are, in literally every social media situation, on literally every post that is in regard to some celebrity.
Yes, that is so, so terrible, that he needs to throw a fit, and create even more drama on SNS. How ironic really, considering some of the stuff he's posted. Oh and btw, if you think the Japanese twitter didn't react to his little passive-aggressive post, think again.
Since he doesn't know how to turn off comments, and doesn't know how to ignore them, then stopping is the best.
So yes, please, he can post about a million other things and everyone's happy. Right? No more disrespectful Hanyu fans who can in turn apparently be super respectful on posts of one Oda for example because something or other. Woo.
