His biggest Sin was offending Anita Sarkeesian and Zoe Quinn. Whenever those women are mentioned, and if it's less than pure adulation, they mobilize against their critic. Even if they're not directly involved, companies just don't want to deal with them.
The real problem here is the effect this has on story telling and character development. I want multiple perspectives from a diverse pool of opinions and experiences. If I want stories that focus on intersectional feminism, I can go to Feminist Frequency or read a modern Marvel comic.
I noticed the usual "who cares" or "why is this an issue" posts, but these people are in the minority. They will support whatever Obsidian puts out and do not represent the market at large. After seeing what happened to Tim Soret, among other witch hunts, it's pretty clear that the censors are coming at video games from the left as opposed to the right. This is a serious problem.
Hollywood movies suck because everyone thinks the same. They grew up in the same economic class, most are from big cities, they went to the same schools and studied the same majors. What is the consequence? They tell the same stories over and over with the occasional gender or race swap to "freshen" things up. If Obsidian is capitulating to the Zoe Quinn's of the gaming industry, then their product is going to suffer.
There are so many games to choose from these days that this news has convinced me not to buy Pillars 2 at launch. I will wait for a price drop which should give me enough time to find out if the writers are a bunch of sanctimonious SJW preachers.
