As far as i remember Nyx never told much about what she has planed, except there will be a darker path, eventually.
Some said walking by Erynn, not helping her, was what lead to a darker path, now Nyx said the choice with stealing Ethans phone is what lead to a darker path...and it was canceled because it's too much work.
She also said, some characters won't survive, so no idea what her idea of a darker path even was...
Also Nyx changed her plans already a few times, like Alexis was just intended as a fling now she is a main girl.
Nikki should have died in a car crash etc.
Add to that, Nyx is not really a reliable source if she talks about the story, she likes to tease, fuck around and rile up fans and supporters way too much.
So besides speculations, i don't think anyone of us even knows much about that ominous dark path, i doubt she cancelled her plans because of ntr complains, could have just as well be that she thought it would violate the patreon tos (rape) or that she would ruin her income ¯\_(ツ)_/¯
