I'd say politics and cost of living/doing business are the two primary drivers for this move. Secondary drivers are likely regulatory environment, future uncertainty, and as stated, the potential to produce some things in Wyoming which can't be produced in California. I'd bet there were more than a few personal considerations, as well, such as family suitability, proximity of hunting/fishing opportunities, and perhaps even some religious considerations, but that's just conjecture on my part. I know it's tough to be Christian and work for a California-based company, from personal experience. Plenty of discrimination goes on, both overtly and subtly. I'm sure the business to business and business to government climate is no different.
