Microsoft continues to block competition by creating PC marketplace confusion. One version of Windows 8 blocks the owner of a computer from installing a competing operating system such as GNU/Linux. A second version of Windows 8 (that looks the same) has the capability to block alternate OSs, but this capability is disabled by default. This leaves the consumer in a state of doubt: will I be able to wipe Windows off and install a different operating system or not?
Microsoft utilizes fear, uncertainty, and doubt to intentionally circumvent the Department of Justice ruling against it from 2001. The consumer is left feeling that Microsoft products are the only viable choice.
