I see Intel has just released the previously-commercial-only Threading Building Blocks (TBB) template library under GPL v2. And this has reminded me of the complications Qt has brought up being v2-only, and it suddenly occurred to me that there's a way MS could bring a really sneaky anti-v3 strategy to bear.

MS has a number of proprietary things that the FOSS world would like to get inter-operable. The NTFS file system. The Office formats. Etc. etc. And the EU has been nagging at them to release interoperability information for ages.

Since MS seems to really dislike GPL v3, they could solve a lot of their problems with a simple move: Release all the code necessary to get interoperability under Linux working. Under GPL v2 only.

Take Samba.
