I'll add to your comment that Microsoft is a known, patent troll. They can give a business something free under MIT, wait until it makes a fortune, and then sue them for same code in patent courts. License like Apache 2.0 give a copyright and patent license for the code. Makes such scenarios impossible. Whether they'll actually do it or not is an unknown. I'd prefer we default on licenses that nullify the patent risk.
