Why Google is not concerned with distributing public key?

google is not overly concerned with distributing public keys because they utilize established protocols and systems, such as HTTPS and Certificate Authorities, to manage secure communications. These protocols ensure that public keys are verified and distributed securely, minimizing the risk of impersonation or man-in-the-middle attacks. Additionally, google implements advanced security measures, such as certificate pinning and the use of its own infrastructure, to enhance trust in their public key distribution. This layered approach helps ensure the integrity and confidentiality of user data without the need for direct public key distribution.
