Purchasing a flight sim, am I being overly paranoid?

Assalamu Alaikom, I enjoy playing flight simulators. I have come to find out that the developer of one of the military flight sims I have been looking to purchase also has military contracts on the side. Meaning they develop specialized, private sims for use by a couple of air forces for training purposes (all non-Muslim, and who have actively been involved in campaigns on Muslim lands). Does this make it Haram to purchase from said developer? Would there be (indirectly) blood on my hands? Where do we draw the line?
