This podcast warns about the privacy risks associated with WhatsApp, owned by Meta (formerly Facebook), despite its widespread popularity. The author points out that while WhatsApp offers end-to-end encryption, it collects a significant amount of unencrypted metadata and can decrypt messages in certain cases, in addition to sharing data with other Meta apps.

Recommendations are provided for configuring the app more securely, although more privacy-focused alternatives such as Signal or Threema are suggested. Finally, the podcast emphasizes that WhatsApp's business model appears to depend on the exploitation of user data, as evidenced by fines and controversies.
