Complaining about a "culture of liability" makes no sense in this context. The legal system doesn't create liability for posting a bad review--it just enforces the voluntary contract you made with someone agreeing to that restriction.

What you're actually asking for is the legal system to intervene and invalidate certain types involuntary agreements. Which I would agree with. What we live in is in fact a culture of excessive insulation from legal liability! 99% of all those "contracts designed not to be read" that the parent poster complains of, those TOS you have to agree to just to use hardware you paid for, those are designed to make you to sign away rights you have under tort law.
