I don't know about anyone else, but helping to protect the confidential data of millions of users around the world seems a very large reward for uncovering a hole in the encryption algorithms of M$ products.

If it means protection only when using a proprietary product owned by Microsoft then no, I still don't see it as much of a reward. If we are talking a system which can be used by everyone at no cost, then yes that would be motivating.
