That post is full of so much bullshit x'Dx'D
The reason it didn't help DMD was because the dev was way too fucking obvious with everything. Take a look at a few other games like Dreams of Desire, nobody is bothering the devs after they removed the incest content and didn't blatantly write on their page "Don't worry guys, we'll give you a patch to restore everything".
If they had just removed the relations and released a patch on another platform like lewd patcher WITHOUT writing anywhere that it was something else but a fan project there wouldn't have been any problems at all. The reason Big Brother was abandoned was simply that Darksilver just didn't want to continue it, simple as that.
