The reason for these folks unionizing is not for the traditional reasons (higher wages, better benefits, work life balance, keeping the company from running you over, ect...) This is more along the lines of being able to protest work that is consider unethical (IE the AI noted in the article, working with other gov'ts ect...) and not be penalized or fired for it. Unfortunately, I don't believe that a union is the answer for their problem because so long as there is money to fund a project there will be people lined up to work.
