Yet folks often say their $0 software is free software because gratis. Words evolve/change & only mean what the folks think it means. If anyone wanted to take over a word, they could. To say it’s not open to interpretation is silly. To assume the ideas they first put out long ago never need a revision or update or were infallible missing no changes to software/society is a religion. Right now we see folks come to terms that outside GPL, a lot of code is being used for AI training models & then sold while not giving users a hint at who wrote it or where to get the source. These ideas probably need to change & projects like Peer Production or Blue Oak or License Zero feel they want to actually take on your enshrined terms like “free” & “open source” because there is not a better word to describe what they are proposing, then I don’t see a problem other than possible confusion (but folks might be confused either way like saying those licenses are nonfree just because a for-profit entity can’t use even if individuals, collectives, nonprofits can).
