As I said in other places, that is a serious matter and puts such information at serious risk in any circumstances. Whether or not Windows phones home is irrelevant if the people handling classified information are allowed to do so in a careless manner. The problem of classified information being on a system where it could be set back to Microsoft in the manner described in the article is that the information is on that network in the first place, not that Windows might send it to Redmond. The latter just makes cleanup and remediation a bit harder.
