I am not trying to gaslight you into thinking that there aren't trends like this in gaming, I am just trying to explain to you that it is a wholly separate concern from "DEI" and these two things have been conflated dishonestly by grifters who want to make it more of a conspiracy of elites, because that narrative makes better ragebait.
These decisions are usually made out of commercial interest, honestly. There is a belief that this will help them appeal to a broader audience, and to some extent it's also an effort to appease potential backlash for a lack of representation or insensitive representation. It's not because investors or DEI departments have pressed them, they don't give a shit about game content.
Unfortunately they're now kind of caught in this now-win situation where they have to offend one side of the culture war or the other. All of you culture warriors on both sides are basically strangling gaming, and we're seeing the effects.
Again, you're not wrong about increasing representation in gaming, but it isn't about DEI departments or investor money, it's a cultural phenomenon that you aren't parsing correctly.
