Your right to privacy is an unalienable right.
Unalieanable rights are rights that cannot be taken away, not even by a 100% majority vote. Unalienable rights cannot be legislated away, and they cannot be ruled away by a supreme court. They cannot be contracted away. Governments and institutions cannot add qualifiers to unalienable rights, and they cannot dilute them. They have no authority over unalienable rights.
Ignore their laws and their dictates. Chat using end-to-end encryption and refuse to give them any keys. Use your own servers if you must.
Non-compliance is the only to guarantee your unalienable rights, freedom, liberty, and individual free agency.
