You can safely ignore anybody blaming anything on "diversity quotas" since all the hires at the decision making level in Hollywood are nepotism or coke-buddy based.
So, this point: naw it happens.
For example, that's what killed Amazon's
WH40K series. They had actor diversity quotas they injected into the mix that went totally against the lore, so Henry Cavill walked on it (in case you're curious... the Adeptus Custodes are all male according to lore, but Amazon wanted some female ones... Cavill, who is probably on the spectrum, got pissed off. That's why GW is making female Custodes figures now and gaslighting its customers).
Vikings: Valhalla replaced a well known Scando jarl with a black woman.
Both Helen of Troy and Joan of Arc are now black, in case you didn't know.
So, yeah... diversity quotas are a thing, BUT... Roddenberry played the same game in the 1960s except better. He put a racially diverse crew on the bridge because, as Uhura put it "we've learned to be delighted with who we are." That's not the same as saying "race doesn't matter."
Building on that, he went against some racial stereotypes... putting a black woman on the phone, having a Japanese guy driving, etc.
Dude was psycho, but creative. We need more of that, not erratic shitlibs like Kurtzman.
