I think about this semi-constantly, and have a lot of trouble getting most of my friends to factor these kinds of issues into their world view or consider their importance. I'm too young to remember the crypto wars of the 90's (I was a kid back then), but I'm well aware of them and bring them up fairly often when talking to peers about the background pushes against encryption that constantly happen. I also make a lot of personal effort to rid my life of resources owned by large corporations, but I often wonder if there is something more I could be doing to resist these things.
