I think we're arguing what is morally correct while you're arguing what is legally correct. You're right legally, but it still sucks that everything has to be defined to the Planck length and you'll still probably get screwed.
The implication is that both sides don't necessarily have leverage, meaning you cannot force fair behavior by yourself. This power disparity is something society at whole tends to recognize, and is thus able to leverage social norms to shame a company into behaving align with societal understandings of fairness.
