It doesn't really change the fact that quite a few militaries license "MCS", the military version of the simulator for training purposes (and it probably funds DCS development as a side project).

You could even see it now in photos with Ukranian pilots, most likely for F-16 cockpit familiarization.

Remember that pilots spend quite a bit of time practicing on printed out posters of cockpits and DCS is quite better than that ;)
