I'd argue any contract is problematic if there is both a significant power discrepancy between the parties, and the terms are non-negotiable (take it or leave it).

When I think of the word "contract" I don't picture two companies with a meeting of the minds, on equal footing, settling something. Instead I associate the word with a hammer that a powerful company uses to smash a relatively powerless individual--because that's the only kind of contract 99% of us will ever be party to.
