Seems to be a US thing. Apparently people can give up their rights and consumer protections by agreeing to a contract. Naturally, these "you agree to not exercise your rights" clauses have become standard in privacy policies and terms of service. In many other countries, a judge would simply invalidate the abusive clause.

Very few people are going to take this to court though. Regulators need to establish rules and proactively enforce compliance in order to bring about change.
