The frequent requests for email addresses and personal data by websites and services can be criticized for several reasons: 1. Privacy Concerns: Constantly providing personal information, including email addresses, increases the risk of privacy breaches. This data can be misused or accessed by unauthorized parties. 2. Data Overcollection: Many services collect more information than necessary, contributing to excessive data accumulation without clear benefits to the user. 3. Intrusiveness: Repeated requests for personal data can be seen as intrusive and disruptive to the user experience, especially when this information is not essential for the service being used. 4. Potential for Spam: Providing an email address often leads to unsolicited marketing and spam, cluttering users' inboxes and potentially exposing them to phishing attempts. 5. User Autonomy: These practices can undermine user autonomy by making the sharing of personal data a prerequisite for accessing services, often without providing clear alternatives or opt-outs.
