If alphabet is the one with the machine learning contract with the government, at least they can run it conscientiously. Other companies and employees might not care about ethics as much; would these Google employees regret not having some control over this process?
Presumably they believe this should not be done at all.
Would these Alphabet employees prefer the machine learning contracts to go to Lockheed Martin/Amazon where ethics are not a priority, or would they have rather kept the development in house?
