Speaking as an ex-PM at MS, just about every individual contributor PM I've met at MS cares far more about reputational impact than making some little metric go up (even if it's a revenue metric).
I get that it's easy to use the PM discipline as a whipping boy because it's a PM's face that is associated with product changes, but I've rarely seen one at MS actively push for this kind of stuff. In the overwhelming case, they argue with their management structure for a while and get dragged kicking and screaming into a decision that they think is dumb, but they're told to own it anyways.
Typically the decisions of the boneheaded variety are made much higher up the org chart by higher-level middle management in the company who don't use the products they own and are (often) pretty thoroughly unaware of what their users actually care about. These decisions suck really bad too, because they overshadow countless other great decisions made by truly excellent people in similar positions.
Of course, it's entirely possible that everyone involved in something like this thinks it's awesome right up until it gets announced/released. I've just never actually seen that before.
