“Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.”
You see this on many electronic devices sold in the United States, and I think it’s actually a pleasingly crisp formulation of the “golden rule” in terms that make more explicit that such a rule mandates that you accept things from others that you yourself should not or are not allowed to do.
