I'm going to address your specific link.
Microsoft has different classes of customers and the functionality that you don't want, many customers request and may even require. You aren't obligated to use their disk encryption or functionality. You can install your own WDE product, but you appear to want the features of a Ferrari for the price of a Ford Focus, which is not reasonable.
Microsoft is not trying to mess with your system via that method. If anything, that is a blanket improvement prior by default there was no encryption. Could the design be made better? Maybe, with any implementation of a security feature there are always trade-offs. Microsoft could force users to store the key locally or print it, but then millions of people would simply turn encryption off or lose their key. This does not grant MS remote access to your system.
There are plenty of things that are wrong with MS, but saying Windows is malware is FUD plain and simple.
