That's not what stalled the development of web standards. That's what helped them win the browser wars, during which, mind you, nobody was really trying to follow any standards. Everyone was racing to introduce proprietary features. Microsoft won partly by strong-arming OEMs into not pre-installing other browsers, and partly by simply building a better browser. But just as they won, they got sued big for antitrust, and they let IE languish, which may or may not be due to the lawsuit. This was what slowed adoption of new features because sites were overwhelmingly designed for IE, and IE was not improving at all.
