I believe this was the article that discussed Microsoft's issues when attempting to implant their management style onto studios they've acquired in the past and why it failed to work:

"From the inside the studio's gates, too, the changes to Rare introduced by Microsoft tampered with the recipe of the company's success, leaving teams feeling disorientated, and even downcast.
"The changes were imperceptible at first, but became increasingly rapid as time went on," says Phil Tossell. Hired by Hollis in 1997, he cut his teeth on Diddy Kong Racing before working as lead engineer on Dinosaur Planet (which later became Starfox Adventures). He was present at the company through the Microsoft acquisition, and was promoted to Director of Gameplay in 2009 when he oversaw development of Kinect Sports. "For me personally, the atmosphere became much more stifling and a lot more stressful," he says. "There was an overall feeling that you weren't really in control of what you were doing and that you weren't really trusted either.
"There was also a gradual introduction of certain Microsoft behaviours that crept into the way we did things: lots more meetings, performance reviews and far more regard for your position within the company," he said. "While these weren't necessarily good or bad per se, they began to erode the traditional Rare culture and way of doing things. Many of the people who'd been there a long time found these changes extremely hard to accept.""

I believe there were other articles with a similar theme.
MS management and decision-making are probably a big culprit here, but the obituary will be written for Lionhead soon enough.
