We haven't discovered memos like this from Microsoft either, but we know Microsoft works with governments. AT&T installed backdoors for governments, and no memo was leaked. Google is a much more leaky organization, with vocal employees, and not very good at internal compartmentalization, and that's why you know about these things. We used to consider a bug if an employee can't 'see everything' everyone else is working on. Is lack of whistle blowers elsewhere a sign that there's no whistles to blow, or a sign that oppressive security and compartmentalized security at other firms makes it hard for the public to find out? My point is, transparency is good, and that more secrecy doesn't buy you trust. That's why people value open source and used to pretty much rail against closed source HW on HN. Now we seem to be an in era where closed source and locked down DRM app stores that block side loading are accepted.
