I'm trying to convey that the whole story of a "free, open, $whatever_virtue" is a lie and the people who tell it are universally trying to get something out of us with the lie.

This line of reasoning takes one in short order to RSA-over-shortwave, which I really think should be more top-of-mind, especially for the weenies who dicker over which native chat app is more secure (an argument that makes me worry my eyes will get permanently stuck in a rolled-up state).
