I really doubt those motives are "evil." They're in the business of selling and supporting an OS. Most people couldn't safeguard a 10-byte password on their own, they're not going to have a solution for saving their encryption key that keeps it safer than it'd be with Microsoft, and that goes for both criminals (or people otherwise facing law enforcement scrutiny) and normal grandmas who just want to not have all their pictures and recipes lost. Before recently, normal people who get arrested and have their computer seized were 100% guaranteed that the cops could read their hard drive and society didn't fall apart. Today, the chances the cops can figure out how to read a given hard drive is probably a bit less. If someone needs better security against the actual government (and I'm hoping that person is a super cool brave journalist and not a terrorist), they should be handling their own encryption at the application layer and keeping their keys safe on their own, and probably using Linux.
