The old "Momica" joke aside, at least your use of "mom" doesn't explicitly look like calling Monica the MC's mother.
Nah, that "a lot of people" just want to play an incest game, which is fair enough. However, this isn't one without a mod that makes extensive changes to make it so. Anyone hiding behind "that's too depressing, so I'll play with Monica as mother!" is just bullshitting.
Almost the same thing happens in the thread for A Mother's Love - People that want it to be an incest game, when it explicitly isn't. Even to the point that there are people wanting the MC's actual mother (alive and well) to become a sex option in game.
Personally I see it the same way as playing an RPG like "Skyrim" if you want to play the vanilla game that's fine.
However if you feel that a modded version of the game make the gameplay experience better for "you" then go ahead and enjoy that.
Personally I didn't really care either way, hell if the script had just been something like:
"You have moved to a new city and are staying with an old friend of the family..."
That would have been just fine for me, I just personally didn't want to play/watch/read a story where the MC's is being taken pity on throughout the game because his mother died.
The incest part of the mod was & is irrelevant to me, just make me a narrative I don't have to cringe over so I can enjoy the game.
Someone provided that, so that is what I play the game with.
If you don't like that some people play the game with a different narrative due to a mod, that's fine.
But there is no reason take 'shots' at people playing with the mod, just because you don't like it.
You claim that people who have an incest fetish hide behind phrases like "That's too depressing" and call it bullshitting aka lying.
First of all - there is not fact in any of that, just your personal opinion on the matter.
Secondly - I personally haven't hidden anything, I like incest tagged games most of the time, they are not a main reason why I would pick one game over another, but at least as I explained above, it was minor reason in regards to this game, simply that it changed the narrative.
