Correct. It was a poor choice of words. s/affiliated with/an evangelist for/ The implication here is that he may see fewer problems with Microsoft or its subsidiaries, e.g. LinkedIn, having access to stolen personal data than another user who may take a different view of these companies, for a variety of reasons. I am implying he has a high opinion of Microsoft. Contrary to the other commenter's interpretation, I am not implying he shares data with any companies under some special arrangement or assists them in locating dumps. Of course, given his comments that he believes these companies only use such data to protect users, it seems reasonable to imagine that he might not have any ethical issues with doing that.
