Do we copy from Microsoft?

I often hear people saying that Linux geeks copy ideas from Microsoft and implement them.  I won't agree with that.  Nobody is contributing alone.  There are many researchers (from various academic institutions, not specifically from Microsoft) doing the hard work.  (Take WinFS for eg., it's nothing but derivative work starting from Semantic File System.)  I can also say that Microsoft simply adds some windows-specific bits to their work and be the first player to implement it.  That's all.  They have the resources in hand to be the first, not to allow anybody else before them. 

Hackers usually don't bother such things.  But even our OSS community has started to catch up with this.
