I would want a "People's Republic" of China if and only if we have a Nazi Germany. I want Amplitude to be consistent with its inclusion or rejection of the villainous cultures of recent history. If they want to include a contemporary Chinese culture that isn't engaging in totalitarianism and human rights atrocities, I'd much prefer the Republic of China (even if it's called Taiwan).
There are different stages of breaking human rights, not immediate jump to Hitler, and your standards would make it impossible to add any modern state to the game. China had Mao, Tiananmen and Uyghurs, Pakistan genocided Bangladesh, Japan did ww2 (and is not apologising to this day!), South Korea was human rights breaking dictatorship until 1980s, Thailand is authoritarian, Indonesia did like three separate genocides, Vietnam did massive purges, Iran hangs gays, Turkey does genocide denial, Russia was terrible for an entire century, Germany did ww2, UK did Bengal famines, France did Algerian civil war, Israel did Palestine, and US killed hundreds of thousands of people in its right wing pro - dictatorship coups during cold war. So what, are we supposed to not have any modern cultures? Even Canada and Sweden (paragons of human rights) sterilized and persecuted Indians/Sapmi until like 1970s. Brazil killed a lot of indigenius people, Nigeria had Biafra war, Saudi Arabia is terrible in general, Spain had Franco, South Africa had apartheid... Almost every modern powerhouse did some crimes against humanity in 20th century, often in 21st as well (say hello to US civilian killings in Iraq and Afghanistan). Let's just ban them all.
But more importantly. The game says cultures, not governments, and I think China in the modern age will be simply "Chinese" - particularly because "peoples republic" or any such exact terms would Clash with the freedom to take government forms. So we'll have Chinese, probably with PRC undercurrents running through it, which is natural due to its sheer size.
Such games and an entire genre always "focus on positives" anyway, and try to depict positive side of history and specific factions and things, it's not like we have a game full of (near universal IRL) war rape and slavery with one faction being whitewashed. Everybody is whitewashed, civ5 and civ6 even do have ww2 era military units for Germany.
