Work there is published if and only if it is in Microsoft's interest to do so. Do you have any evidence for that claim? Often a bare outline is published: enough to impress people but not enough for an outsider to duplicate the work. This isn't academia. Actually, there are plenty of research papers that describe a system in some detail, but not nearly enough detail to allow an "outsider to duplicate the work". Both academics and industrial researchers sometimes accompany a research paper with a working prototype; in both cases, they often do not.
