Except OBS does not have a monopoly. There are tons of publishers of all sizes who sell their own stuff over their own websites (in lieu of obs or in addition).
I recently bought things for city of mist, star trek adventures and several others directly from the "source" (in as so far you can say that with publishers) and it worked just fine.
Not getting into politics here, but the reality is OBS is a business, they keep what sells and does not require effort. VS' stuff is disappearing from there, because he is more trouble than he brings in. The "woke stuff" stays because it sells more than the complaints cost. And do not make the mistake to think this is being driven by loud minorities("complainers"). I guarantee that a business like OBS carefully analyzes these sorts of things.
Same with nike and Kaepernick. They got boycotted, crunched the numbers, released an add with him anyway and had record high stocks. I am not giving moral commentary here, but people generally overestimate how big the bubble is they are in. Business do not.
