"eleutheria" -- old-fashioned by the 2nd century A. D.?

This review of this book on Oenomaus mentions that 'eleutheria', he thought, as confusing. Besides having coined

half-slavery (hemidoulia)

he proposed to analyse 'free' in terms of 'can'

It can rain. The weather is free to rain.
The eagle can fly. The bird flies free.
You can take anyroad you like. Feel free.

Oenomaus's term is "ἐξουσία", which derives from "ἐξεστι"

'Exesti' thing was just a modal. Qua modal, it is important, because it may connect with the modal views of Aristotle, as when he says

potentia -- dynamis
vs.
actus energeia

and so on. Qua modal, this 'exesti' seems to be what we mean when we say
"could have done otherwise".
In all Romance languages, that 'can' do, 'could' have done otherwise, is a form of Latin 'posse'. So it relates to 'freewill'. So Oenomaus was analysing the rather sophisticated notion of 'eleutheria' (freedom, properly) in terms of 'ability' to do, and so on.
