If I have learned anything from history, is that is sucks to be on the losing side of a war. As a worker, I will happily pay taxes and do stuff that helps make sure my side is never on the losing side of a war. As a citizen and voter, I will use my vote and my voice to keep us out of wars that are either unwinnable or unjust. Trying to intentionally reduce the effectiveness of my military as these Microsoft workers are trying to do is not something I will do.
The alternative to US military dominance, isn't a peaceful utopia, it is either Chinese military dominance or Russian military dominance. You can be sure that Chinese and Russian tech companies are trying their best to increase the effectiveness of their country's military.
