Ask Microsoft: Are you using our personal data to train AI?
If nine experts in privacy can't understand what Microsoft does with your data,then in my opinion a court should step in and declare it void so that Microsoft isn't allowed to use any private data until they get their act together.If it's so vague that it becomes meaningless that should default to granting no rights. Otherwise, why not publish your all-rights-granting privacy policy in Klingonian in a locked drawer in a toilet basement? ;)
