If protecting your identity is indeed important to you, consider what these values should be.
One of those ways is obviously when data is breached from a system and all the email addresses are on easy display: address. It's not always that explicit either, for example Ashley Madison returned slightly different responses which could still be observed. For example, when doing a password reset: If you authenticate to another site using your Gmail account (social logins are increasingly common), then you may be prompted to share data attributes such as your name with that site.
