The uncomfortable truth is that this in large part predicated on the culture set by the founders of the company. Only founders have the leeway to dictate what is culturally apropos. Although, I believe that there are strong regional forcing functions that heavily encourage founders to lean one way (in silicon valley, this is usually left). In particular these forcing functions are ability to recruit, form business partnerships and generate positive peer/user sentiment. If you are part of the political out group this can severely hamper your ability to do many of the things necessary for success which is why you don't see any companies riding against the wave (it's hard enough as it is).
