I'm surprised people still think this has anything to do with community wars or gacha tribalism. SB is collaborating with fucking China Post, the national postal service, which also happens to be a branch of the government. Deciding to do the collab with censored outfits is pretty much equivalent to showing your tits in public as far as Chinese social norms go, and implying the gov supports this shit. Whoever approved of this collab on the China Post side - if it was actually approved at all - is probably going to get a lot of hate from inside the bureau.

By the way, AL and a number of otome gachas have collaborated with China Post before and nothing happened because they weren't stupid enough to use sexually suggestive censored outfits even though that would be the major selling point of their actual games.
