It's a joke about how soulless corporations will co-opt progressive language to continue being shit. Some people, either not picking up on the joke or reacting to other people not picking up on the joke, found it might be in bad taste.
Morons found those people and decided "the SJWs are complaining about Doom", coming up with hours of YouTube outrage about a handful of tweets with *maybe* a dozen interactions.
I don't think this is the motivation behind people complaining about the joke.
No, the reason people don't like it is because it is what you describe, but they want to deny that companies do that with all their might. They don't want to accept that all these companies don't sincerely see the correctness of their SJW platform and just naturally follow suit doing "the right thing" but are instead simply making a capitalist, cynical decision to maximize profit. It's kinda like asking them to give up some of their power when we point out that Nike isn't a philanthropic organization but is being progressive just to sell more shoes, because as it is now they get to use the authority of someone with huge backers when they strut around. These people are heavily incentivized to reject the notion that ANY company would do this, and complaining about doom is a form of that manifesting.
So yeah, when you hear this joke, it makes you think of all the companies in the real world who also probably do this thing, and once the doubt sets in, you may even begin to doubt that there could be PEOPLE who are merely espousing these beliefs to promote themselves, purely out of self-interest, and who would abandon you in half a breath if the other side has a larger slice of the consumership.
It threatens the entire foundation of allies that these people rely on to get to command people to do things they don't really want to do.
...yes, that's why I said "a huge chunk", not "every single one of them".
You and I are in very different scenes
Considering I can't come up with any VN where the protagonist is not well-defined, and I have played dozens, it can't be that huge of a chunk. Examples of what you mean in particular with specificity would help. Are you relying mainly on fan-made/doujin works and not professional stuff or something? Cause your account is kinda bananas lol.
