Ok, let me break this down.
Jynx was not "censored". Japan has a long history drawing black characters in a racially insensitive "blackface" style. One they inherited from American media, but while in America blackface has become taboo and unacceptable, this issue still pops up in anime and manga. One of the bosses from Mega Man had to be redesigned to look less like this stereotype, in 2006
. So in 2000, A person named Carole Boston Weatherford wrote one article about the history of racial stereotypes in anime and manga, and used Jynx as an example of what those kinds of characters looked like. Jynx specifically has been said to actually NOT be a caricature of blackface, but instead a reference to Japan's "ganguro" subculture. But given Japan's history on the subject, I don't think it was unreasonable thing to question or examine. So one person in one article said "Hey, Japan has a history of doing thing, Jynx kinda looks like thing." And Game Freak said "No, Jynx is not thing. This is just a cultural misunderstanding and we apologize. We will change Jynx's design a little to make it clear that it is NOT thing." That is NOT censorship. No one forced them to change anything or remove anything against their will. They chose
to change it themselves of their own accord when they realized something about their creation was unintentionally problematic. To make pokemon more inclusive. That's all. This trend of calling any change in a medium "censorship" regardless of the reasons for or motivations behind the change isn't a good thing for two reasons. One, because it risks dismissing genuine concerns from marginalized groups of people and two because it diminishes the actual importance of stopping REAL censorship.
