The truth is that none of their actual EN fanbase is upset about the increase in JP content. This is normal for ENs with a large JP viewership and they have the largest. It has never caused controversy before.

So who are the people complaining? It's mostly the (usual suspects) SEAdonesians and chinks seething with jealousy that vtubers like to cater to English or Japanese instead of their stupid fucked up gobbledygook languages.

Also as always a healthy chunk of it is falseflagging Nijinogs.
