Is there a word or expression for this idea of not relying on big corporations for one's cyber presence, communications and other such tools? I thought about info-independence, but I'm sure someone smarter than I already coined something better by now. I know it is (always?) open source, but not everything open source liberates one from the cloud giants. So there's something there that needs a name, I think.
