Contractual agreements that conflict with Christian belief

The above include the use of online platforms, employment contracts, and other official documents. When signing up to use online platforms the user is required to agree to a set of terms which includes an agreement not to do anything illegal. Since what is legal is not always moral and vice versa, how can a Christian agree to such terms? Similarly, the residence permit application for China contains a box the applicant is required to tick that they will obey the law of China, which includes restrictions on speech and an injunction to have "religious" meetings only in government sanctioned buildings.
