In order of increasing goodness:
1) Microsoft makes no promise about encrypting data whatsoever
2) Microsoft encrypts data weakly, keeps code proprietary
3) Microsoft encrypts data strongly, keeps code proprietary
4) Microsoft encrypts data strongly, open sources relevant code so community can validate it
So Microsoft announces they're going from 1 to 3. You're paranoid and saying maybe they're going from 1 to 2. Fine.
But here's the thing: it's still IMPROVEMENT. Maybe it's not as much improvement as you want, but people are posting in this thread as if somehow Microsoft got worse. But they didn't. They got better.
So to answer your question:
If Microsoft told you they were implementing security and it turned out they were using DES with a key hashed from the word 'Scroogled', would you be pleased?
Yes. Because that's better than them making no promise whatsoever about data encryption, which was the situation a week ago. I am pleased. Thanks for asking.
