If you wanted to avoid companies that have any sort of collaboration with the military, your software setup will look quite…small. You couldnt even use Google in any form (see i.e. Boston Dynamics).
Please note that i am not a general supporter of military actions in any way; But from a neutral point of view:
The good thing about military is that it often drives technology. GPS wouldnt exist without military as an example. Many inventions were originally made for the military and used for public stuff.
