This reads to me like a story about corporate malfeasance, exacerbated by the fact that the industry relies on so many casual, freelance workers. Exacerbated again by the fact that fans of creative products get territorial about the companies they support and that discussion about it becomes a proxy for the culture wars.
It's illustrative that several of the things she describes are, if true, outright illegal. Even the carpet thing has to do with worker safety. And yet it is unlikely in the US that a handful of employees are going to be able to successfully sue even a small corporation like Paizo on that account. We need better regulations and workers, including freelancers, need unions. Consumer recourses are, in my opinion, weak. That said, maybe focus your gaming money towards independent creators and smaller companies?
