What role should ethical considerations play in web and app design, especially in terms of user engagement and persuasive design tactics?

ANSWER: Ethical considerations are paramount in web and app design, ensuring that user engagement and persuasive tactics respect user autonomy and privacy. Designers should promote transparency, avoid manipulative features like dark patterns that trick users into unintended actions, and safeguard personal data. By prioritizing ethics, designers can build trust and foster long-term relationships with users, leading to sustainable engagement rather than exploiting short-term gains at the expense of user well-being.
