On the flip, there are many hackers who are religious. Despite popular consensus, hackers are people and some 80%+ of the world population claims one religion or another. It only serves to reason that some of this 80%+ of the worlds population would call a scientific discipline, such as programming, their trade of choice.
Although a generalization for sure, there is likely a grain of truth and logic to the posed argument - specifically, fewer hackers are religious than is the case with other disciplines (such as, say, insurance agent).
I know a great number of hackers who claim to be "religious", though philosophical discussions often show them to hold concepts more akin to agnosticism. My (unscientific) theory for this phenomenon is the "fire insurance" argument - i.e. If a particular religious system is correct, denouncing the legitimacy of said religion will ensure them a place in hell. If the individual does not formally denounce said religion (despite the religion not necessarily syncing with their true beliefs), they can still claim a place in heaven as a 'believer'. The "if there is a God, I am good, if there is not, what did it hurt to pray?" defense.
To each their own I say. If it works for you to believe, then by all means, believe. Concerning science and religion, evidence suggests if there is a God, he like to play dice - something that many notorious religious scientist were uncomfortable with. Myself, I find comfort in the randomness.
