Could have, had plenty of time, didn't.
Dark Silver said it himself, the incest fetish isn't his thing.
He abandoned the initial version of Glamour that he was working on (a non incest game), then started Big Brother, even going as far as calling it "The incest adventure of your life"...
Add 2 + 2 and get "did it for the money".
Those comments are at least partially correct. The degree of how correct is certainly up for speculation.
He announced that work would be done on a remake of Glamour, whilst still doing Big Brother. This was met with a mixture of "He's using Big Brother to fund Glamour" to "He's going to be finishing Big Brother and have Glamour ready to release early versions without downtime", or at least words to that affect.
Then the ban hammer came wandering his way, and already had some early work done on Glamour, released the current version of Big Brother, along with promises of finding alternate funding because (based on what he publicly said) Patreon wouldn't allow Big Brother in any way, shape or form to have a presence on Patreon.
Shortly after was the first release of Glamour.
Whilst many expressed displeasure over a female protagonist, more expressed concern and (arguably justifiable) vitriol over how Glamour would have its updates released - online only "in game" downloads, as opposed to releasing updated versions each month for separate download.
After a few months of hearing absolutely nothing regarding the future of Big Brother from Dark Silver, the game was officially labelled here as Abandoned.
As for dick moves, there was some more relating to Glamour, but since I'm not following that game's development, I don't know what they are/were.
