Whether they care about consumer market or not, they know that most of the consumers aren't going to care about this problem. Hardly anyone would bat an eye at using their already existing Microsoft account/email address and internet connection to log on to their PC. They're almost 100% headed to get on the internet to do whatever anyways. These people are connected to the cloud 24/7. In the same way hardly any Apple user cares that they need an Apple account to get into a bunch of things/phone/whatever. This is a nerd/tech-niche problem.
