Whenever these things happen, it's always a "mistake", "accident", or "bug" when the outrage is beyond what they expect. If it's limited outrage, it's labeled as enhancing the user experience. And even if it's massive outrage, that "mistake" is added back in a year or two later and never removed.

I think someone should track the ratio of these mistakes/bugs that directly or indirectly benefitted MS vs those that costed them.
