No it isn't. The scale of the problem would be completely different.
I'm thinking of it this way. If a hacker finds an exploit MS doesn't know about and gains access to the system, that's practically an act of god. There's no such thing as a 100% secure system. I can forgive that. If MS stores passwords such that any random customer service rep can actually read them, that's a bad thing that is their fault. Further, if they are letting CSRs give out existing passwords over the phone, that is inexcusable. Like I said, I don't think that's what is happening, but if it was I would not be very forgiving.
