Want an actual speculation based in reality?
I think it has to do with the fiction within the corporate culture of Microsoft that is leading to a lot of bad decision making. There is a Dragon Lady, not naming names, who was brought in as an HR head (or similar position) to tighten things up. She has been responsible for a lot of layoffs and good people leaving the company due to the toxic measures she's taken to try and optimize executive processes. She is proud of this fact, feeling that her accomplishments have cut the wheat from the chaff. Many good people disagree.
Under her direction, people have been laid off in manners reflecting the structure of reality television eliminations. During decision meetings, she would have employees submit ideas and vote, in a quasi democratic fashion on which ideas would succeed and who, if repeatedly submitting bottom ranked ideas, would be let go, in the name of performance management and incentiveising career driven atmosphere.
Forbes and a couple other publications took a look inside at recent procedure and illuminated these issues.
It's a problem because it turns the workplace competitive, instead of collaborative and ideas that can be best sold on their popularity within an insulated system for the benefit of individual workers. It's obvious how this sort of system could harm feelings of trust, security and good will in the Microsoft corporate ecosystem.
In the spirit of 'tightening things up' and encouraging internal competition, they've added nothing but noise and friction to important decision making processes. It hurts the company, consumer and it's employees. It leads to bad decision and a bad work environment. It has cost people friends and jobs and will cost Microsoft profit and share value.
Hope this changes.
EDIT: This post is based on my understanding of somewhat dated information, so I could well be wrong, but I think it's still going on and would explain a lot of the high-popularity democractically stupid ideas Microsoft employing.
