The leap I seem to have trouble getting to is this. If you can't trust the people responsible for the proprietary software, how can you be sure that they won't turn around and start using new chips or software once the existing ones are reverse engineered? Perhaps it's about patents and the patent holders could be using this IP as a cash cow?
I think about 50 years ago there began a slow shift from warnings of overt totalitarianism (1984, Brave New World, Fahrenheit 451) to threats of social fragmentation, economic inequality, corporate surveillance and other indirect forms of control, the resulting loss of individualism and, of course, ecological collapse. These issues seem to remain relevant for the foreseeable future.
I also believe that no one really understands how the world works, not even the elites. Incidentally, this is the most powerful argument for democracy that I know of.
There are a number of others, though as well where the recurring theme seems to be the "evil elites" leaving the poor to fend for themselves.
Definitely agree, no one "knows" how the world works. I don't think the OP presumes anyone does. The intention in saying this was to point out that there are some (these days it seems many) who are off the mark in an almost tragic way, and have no desire to reflect / improve on this.
Pull the wool back a little, peek outside, and see how the grifter techbros are still pushing for that bleak dystopia where they will feel validated by the masses who haven't hoarded billions in wealth.
I'm still dabbling but have kind of latched onto the idea of using Ceph. To my understanding they were acquired by RedHat, and the project has all the signs of real open source, including the fact that it originated as a doctoral research project at the University of California, Santa Cruz, with initial funding from the U.S. Department of Energy.
