Confused is not the worst outcome. It brings the possibility of thought, and even knowledge-seeking.
"Free Software" does not confuse.
"Free software" means ad-supported, tracker-infested garbage from an app store, to normies.
"Freedom Tech" is my favourite term, but "Open Source" is #2.
I like "open source" in most every day situations as a dev but when the discussion gets into rights and licenses then the actual meaning of the words becomes much more important
That's true, but what we think "free software" means and what normies think "free software" means are not the same.
This is not going to get better. Please just confuse them instead!
It's unfortunate that gratis and libre share the same word in the english language
