The amount of people who actually care about "free as in freedom" software are a small group of a small group of nerds (programmers).
I think that's wrong, and with the macOS fiasco from a few days ago (https://sneak.berlin/20201112/your-computer-isnt-yours/) I think that there is a potential here, while digital privacy is a much wierder battle: People semi-conciously give up privacy for compfort, and I don't think they are wrong. Most people just don't have that much to loose from producing adversiting-data.
