Modern audience means woke, in other words heroically portraying white male characters as incompetent and evil whereas non-whites, women and especially the gender-confused are enlightened saints. It goes hand in hand with bottom tier writing of course, similar to when writers talk about the game being "mature" which means there's a character who can't speak without innuendo, something you may recall doing when you were twelve and may now recognise as being the exact opposite of mature.

TL;DR "modern audience" means it's probably not for you.

It means the company is virtue signaling to advertisers, share holders & potential investors - it's a great ciclejerk, under the patronage of Blackrock, Vanguard & State Street, the pushers of ESG/DEI. Many people use such products it to launder money, dodge taxes or for good ol' bribery, just because gays & blacks are involved in the whatever (that's the pretense).
"Modern audience" means nothing, it's a political agenda masquerading as an investment framework; a ~legal scam, basically.
