'unfairly-released' originates from the combination of 'unfairly' and 'released', where 'unfairly' is derived from 'unfair', meaning 'not fair', and 'released' is the past participle of 'release', meaning 'to set free'.

'unfairly' evolved from the Old English 'unfæger', meaning 'not beautiful or pleasing', and 'release' from the Old French 'reles', meaning 'to let go'.

Initially, 'unfairly' meant 'not beautiful', but over time it evolved to mean 'not just', while 'release' has maintained its meaning of 'to set free'.
