Hi 4321,
When this thing started out, MS and everyone else assured the world there are no back doors in the system.
Now, of course, it turns out MS is the US government's tool for back door entry.
If every sovereign can have access to the system via some remote server, then the system itself isn't viable.
If it cannot protect corporate and national secrets from the US and China, why bother moving stuff into it?
The only way to create a workable commercial system is to make it actually secure in a network setting. At least secure unless it is physically stolen.
Most folks don't want the NSA spying on them. Thank you, Mr Snowden.
