Tbh i find it kinda insane thought that a subliminal you play on ur yourself at that would in any way compromise free will of someone else, as if thats a thing or a small public company would have the knowledge to make some mk ultra cia mind control stuff then everyone eventually could.
If anything free will scripting in my opinion is just self assurance for the user to be able to accept for themselves that someone desires them for themselves and not something external like a subliminal.
