Sure, but that doesn't mean it would not be possible to develop such technologies without military research. There's nothing about people with guns that is necessary for communications research.
Having said that, I just posted across thread on why I think we still need the people with guns, so if that's the case we might as well take the incidental benefits where they come.
Saying we should eliminate the military is the geopolitical equivalent of rewriting your service from scratch. The military-industrial complex is the system we have and know. Another system might work but there is no reason to believe the costs of developing it would be less than fixing bugs in our current implementation.
