I disagree with your premise. For many people this will force increased personal security and make their accounts more easily recoverable in case they forget their passwords. I'm something of a security expert, having consulted on architure implemented by several of the largest anti-virus distributors and retailers in the world. My honest opinion is that people need a dramatically better understanding of how domains work. If they want the increased privacy they should need to understand how to setup and use a local domain well enough to find the new location for creating a local account. For those who cannot do this, their device security and therefore personal privacy is far better served by registering a microsoft account. Any privacy concerns stemming from trust should be addressed by laws governing the acceptable use of user data. California is already pursuing such laws, and we should be supporting those efforts because they are addressing the true root cause of most modern privacy issues.
