Working on missile guidance? Then I can see your point of view... but everything else in some way facilitates or contributes to facilitating such things.
One can rapidly reduce it to "fixing a Linux bug... facilitates the military industrial complex". You might wish to not work on things that directly are used by the military, but the vast majority of technology is indirectly used because the military and their supporting companies, processes, logistics is so broad that it's almost everything.
At which point can you say your work truly does not facilitate or contribute?
