The content is given to you on conditions outlined in Terms of Use. If you a agree to the terms, but later violate the terms you are breaking the contract, thus violating contract law. If you manage to avoid getting into contract by side-stepping "I agree" button, you are obtaining content without a license, hence violating copyright law. The act of side-stepping can be construed to mean "unauthorized computer system access", aka "hacking" or "cracking". None of this is likely to get you prosecuted, but then if prosecution is all you care about you could use other means to obtain content which are also not very likely to get you in trouble. This is not a legal advice, I am not a lawyer.
