The phrase "cracks down" implies an action taken to suppress or control something. It is always associated with authoritarian or punitive measures. The antonyms for "cracks down" are "tolerates," "accepts," and "ignores." When you tolerate something, you allow it to exist without trying to control or change it. When you accept something, you acknowledge it as it is, without trying to enforce any regulations or restrictions. When you ignore something, you deliberately overlook it, without taking any actions to suppress or regulate it. Therefore, the opposite of "cracks down" reflects a more liberal and lenient approach, where the emphasis is on freedom and individual rights.
