Not sure how people just feel comfortable with white lies and not acknowledging their wrong doings. If flesh trade is a thing then so is this intellectual prostitution. For me I tried and got fired twice, now just staying silent...
Thus as a professional you should refuse to engage in illegal, unethical conduct. If management remains unmoved, then resigning is really the best long-term option. The stress of any wrong-doing is bad for your health and in some cases, you could be liable to prosecution for your actions.
