Completely agreed :-)

Definitely. They already began to pull some people like Ian Murdock. And 
I'm really very disappointed of this move,Ian did. Especially, such a 
person who has very good reputation and high profile in the Linux 
Community. He immediately shut down his company (also leaved 
Linux-Foundation) and joined to sun. After joining, he made statements 
like "How to make Solaris more like Linux ?" etc. Like a 40 years 
employee at Sun. Another interesting thing is the timing of this hiring. 
So, this situation is a good example of it.

One more time,agreed ;-)
