Will Microsoft Go After Linux, Again?
Microsoft just purchased 882 patents from Novell, and I think that amongst this treasure trove is something Microsoft wants to use against Linux.
It's not a huge secret that Microsoft hates the entire idea behind open source software. It thinks it's a monster that creates free products that erode Microsoft's commercial offerings.
The company can tolerate many of these packages, such as Open Office, because they are simply not as good as the Microsoft product and the company knows that people who use something like Open Office will often migrate to Microsoft Office when they can either afford to do it or must do it.
Of course, when it suits Microsoft, it will use various chunks of open source code as needed.
