I think this is true, and also a lot of tech, which often isn't as PR as the web/internet tech, gets funded by DOD/DARPA

That being said, I feel like a lot of the web-based tech, device tech etc came out of the liberal/leftist university environments, i.e. BSD unix, CERN, linux ish type projects. Berkeley/Stanford/MIT etc. So the culture of a lot of people who were rank and file and enthusiastic about this stuff from had this mindset.
