But only for security reasons (apparently).
“Protecting your account from unauthorized access and fraud is a top priority for us. It helps keep Xbox Live safer and more secure for everyone. That’s why the TOU now asks all users to commit to keeping their contact information up to date. By the way, now is a great time to make sure your security proofs are valid and accessible to you.
“More app experiences available via Xbox Live are provided by a partner with whom you may have a separate online account. If you choose to link this account with your Xbox Live account, we confirm key data points across the accounts by sharing data such as your name, address, email address and date of birth with the partner. In this TOU update, customers agree to allow Microsoft to share this information in this manner.
