What is needed is a system backed by a company such as yahoo. As long as it achieves the end goal, and starts to sort out the spam problem, then I say go for it.
To be fair to Microsoft, this information is only passed on when you sign in with your passport. I find it quite useful to be able to log into a site with passport, and I have instantly set up all the information I need to get started. No need to wait for an email, and reply with a code, or one of the other ways sites require you to register.
At the end of the day you do choose where you log in, and it has to know your email(as that is the user name) in order to log in -- this has always been the case. This seems to be allowing you to actually opt out of providing your email if you wished to do so.
