In my opinion, the developer has adequately assessed the ratio of players who like to play the Dom route while maintaining the traditional heterosexual nuances in dominance. Therefore the MC Dom playing the GoodDom/EvilDom routes is only personally involved in domination over the opposite sex. I guess it is all based on the same world-wide % ratio of people who consider themselves heterosexual to people with bisexual orientation. And there are many times more of the former, such is life.
For the same reason, traditional heterosexual audiences who want to push the boundaries of their perception of the "forbidden" and watch porn with trans people usually prefer feminine looking TS models to those who have rough male facial features and a man-like body. The loyalty of many players who hate NTR in porn games to the so-called lesbian NTR, which in their minds is not considered as such, can also be included in the same vein. Lesbian domination can also be added to this "piggy bank". Audiences are loyal to lesbian porn, and to beautiful women in particular.
I'm not a psychologist or medic with a degree, but personally I'd attribute such a thing to a willingness to accept new fetishes without the player/viewer feeling inner discomfort. I'll be honest, the dominance of male MC over other males will cause such mental discomfort to a large number of heterosexual players.
And if we talk about femdom in relation to men, the same pattern can be seen. Those heterosexual men who like this fetish (I don't like femdom) also prefer to see a woman (the opposite sex) as the top rather than a man. This is as true for porn games as it is for regular movie porn. So, in my opinion, it makes no sense to go against one's nature and there are boundaries that people are not willing to cross unless they have a predisposition to do so.
I know. I basically said the same thing, only much shorter.
It's a pity since for me personally I don't care much about gender if it's heavy D/s like shown in-game. I mean whip a ass, male or female doesn't change anything about the interaction.
You do get some view in the later part of the story though, like Zach & Amy contest scene. Maybe with the female pod balancing things, more of the male pod can be seen. Also most early scenes MC was just building up his rank anyway, & now he is in management position maybe?
Anyway, I understood the dev (& your) reasoning, which is why I felt it was a pity, not that it didn't make sense. I also felt kinda weird the pod just disappeared, but a lot of the sub path also seems to be solo like that ¯\_ (ツ)_/¯
Tl;dr:
Would I have liked to see more of the pod in the Dom route? Yeah, sure. Was I unware of the points you pointed out? No. Even my 1st post here I asked about this issue because I expected it already.
Sorry to have made you write so much. I basically agree with the points logically & dev probably does too, which is why gender lines are maintained even in the non-sexual aspects of power & control dominance shown in game. ¯\_ (ツ)_/¯
Edit: I also wasn't specifically talking about male-on-male scenes, or even anything sexual. Just more involvement of the known characters. Like the branding scene, or the Zach & Amy scene. More scenes about the pod, highlighting the difference in treatment between MC & them would've been nice too. (Particularly would've liked to see the chastity chage fitting, in the same process as the branding scene)
But in extension to your points, many ppl playing Dom route might dislike male-sub scenes in general even if it's female-on-male. The dev notes talking about "surrounded by Femdom even in Dom route" made me question if ppl complained about seeing male pod being dominated scenes(like branding scene) on dom route ¯\_ (ツ)_/¯
With the Zach & Amy scene, & the MC getting more power, maybe we will get to see more of the male pod later on, especially with the female pod balancing things out. Maybe MC even gets some power over them (like in the Zach scene. Deciding the punishment is not exactly sexual, but definitely a part of power-play D/s)
