"Microsoft has gotten a lot more subtle when attacking FLOSS. Often it is only through court records or other revealed privileged information that a clearer picture emerges. Without a central repository, a lot of thing just disappear down the "memory hole".
"Microsoft is opposed to Open Source in general - not just Linux. It's not just a competition between two operating systems. Microsoft recognizes the process and philosophy as a threat. If you use, support, or contribute to Free or Open Source, you can not afford to think "Microsoft is not my enemy" - you don't have that choice - Microsoft has already declared you the enemy.
Microsoft has a huge PR effort, that FLOSS just can't match."
