In regards to the previous worries about anti-communist songs, I mean...there might be one or two, but honestly? It's a non-issue. A "nothing burger" if you will (pFFFffF)
Political songs are few and far between in the Vocaloid world. I can only think of a couple in Japanese, one in Korean (where SeeU literally just repeated the word...I think it was "government") over and over? And not really any in English, depending on your definition of political.
The only reason I can think of this happening is there might be a few idiots who want to poke the hornet's nest, or a few people who are genuinely unhappy with the fact that China's horribly, horribly corrupt. Considering that the fandom racism overseas and here has never really been focused on Tianyi (unlike poor SeeU, which still makes me mad because good lord what's wrong with people), I really doubt that spiteful anti-Communist songs are going to be a huge deal.
I predict there'll be a couple, maybe one or two that become popular to an extent, but nothing that should really warrant outrage or upset. Much less enough that would make China kill the Tianyi JP voicebanks.
Not when there's money to be made, amirite? lol
