MS shares information with intelligence agencies and usually before MS has even delivered a patch. On top of it, when we analyze government malware, we don't see some weird calls to rand_s. We just see a few zero-days, exploits for known issues, or just plain-jane trojans. Why compromise rand_s, which could help our enemies and cause a public outcry, when you're sitting on a mountain of zero days? Also, windows is not closed source. MS shares source with governments, universities, etc. I think functions like rand_s are well understood and there has never been an MS backdoor for the government.
