Nintendo fanboys as well as Xbots don't want Sony to buy Kadokawa. Here are some comments on Nintendo Life about it:
I don't like Sony and don't really care for anything they do gaming related, but this would make me like Sony even less.
If Sony is stupid enough to throw away the money Spike Chunsoft makes on Nintendo consoles, that's their problem.
There's plenty of other than Nintendo can make games with.
Kadokawa is a very important Japanese company. If Sony will buy them... RIP Japanese media.
Sony owns Crunchyroll and Funimation. Now it's hungry for Kadokawa. It would be horrible.
If this is true then Sony is just as bad as Microsoft. Enough with the freaking acquisitions already.
This acquisition sounds awful. I don't want Sony anywhere near FromSoft or Spike Chunsoft, they'll find a way to ruin those games or just kill off the IPs and studios.
I've also read that this company owns Famitsu as well... Yeah, this would be terrible. Hopefully this is false or the purchase gets blocked.
Update: Kadokawa acknowledges Sony's offer

Nintendo fanboys hate everything related to Sony, eg PlayStation, and that's the reason why they don't want Sony to buy Kadokawa because they think that Sony is destroying the gaming and anime industry
