Yet folks often say their $0 software is free software because gratis. Words evolve/change & only mean what the folks think it means.

You are still continuing to question a well defined standard meaning over vague technicalities. Lack of gratis/libre separation is an English language problem. That is no excuse to hijack a standard terminology when a better term like 'source available' is present. The only reason for insisting on such hijacks is for deliberate misdirection and exploitation.

To say it’s not open to interpretation is silly.

Oh! So you are going to interpret the meaning of a dollar? Or the size of a legal sized paper? After all, they are centralized definitions and you don't subscribe to any of those. If saying it's not open to interpretation is silly, insisting on absence of standard definitions is sheer stupidity.

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.

You are still beating around the bush. Standardization is necessary. If that's a religion, it's much more acceptable to a world where people live like cave animals who can't communicate anything meaningfully due to lack of agreed upon standard terms.

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

my enshrined terms? LOL! I gave very well defined and well known places where they are defined. Instead, your kind resort to misdirection and dishonesty to exploit established norms. Somebody doing AI training is merely an excuse to justify such malpractices. A tactic those AI companies pioneered and you share with them.
