[Wine] Windows API opens up???

[rygle]

Any thoughts on articles like this one - 
http://www.theregister.co.uk/2008/02/21/microsoft_goes_open/. This mentions the Vista API, but I wonder about earlier API's.

I also saw something the other day about source code for .Net being released as a "learning tool".

Of course, all of this is in a bid to get Office XML approved as an ISO standard. They don't just give stuff away as far as I can tell.
