A few years ago when Google was offering $1m+ stock to counter employees going to Facebook, some people leaked names on Quora but then promptly deleted it. This event is likely one that influenced Quora's interests in this matter. Another factor that likely influenced this decision is that Quora has slowly made some content available to logged-out/anon users. Some sensitive answers written before this product change (e.g. answers on sensitive health issues) were likely written without consideration for these product changes and Quora wanted to ensure user trust could be retained.
