Depending on the speaker, this quote has the potential for reinforcing substantial status quo bias, since taking it serious would dramatically reduce the frequency of truly attempting to speak truth to power. In other words, the quote seems tailor-made for justifying a generalized counter-argument to all speak-truth-to-power actions.

They fashioned a tomb for thee, O holy and high one The Cretans, always liars, evil beasts, idle bellies! But thou art not dead: thou livest and abidest forever, For in thee we live and move and have our being.

— Epimenides the Cretan
