What MS are you thinking of? Back in the day (I'm thinking 20 years ago), anything MS said was law. They had the power to destroy all other browsers so we were left with just IE6 for so many years. MS no longer has that kind of power. They can no longer dictate the technological landscape like they used to be able to do. Now the landscape is dictated by standards and consensus set forth by Google, Facebook, Apple, MS, etc.
