Which action demonstrates a lack of respect for users' digital privacy?

Collecting user data without consent demonstrates a lack of respect for users' digital privacy because it violates the ethical principle of autonomy and the right of individuals to control their personal information. Consent is a fundamental aspect of privacy; users have the right to know what data is being collected about them, how it will be used, and to opt-in or opt-out of such practices.

This action undermines the trust between users and service providers, leading to potential exploitation of personal data for purposes that users may not agree with or may find intrusive. In contrast, practices like implementing two-factor authentication, encrypting personal information, and providing privacy policy updates are all measures that enhance privacy and security, demonstrating a commitment to protecting users' information rather than disregarding it.
