A court has ruled that it is OK for the government to buy thousands of PCs with that other OS without public tenders preventing providers of GNU/Linux from competing. One judge disagreed but it was not enough to open the bidding process. This was a migration from XP to Vista/”7″ so it was a lot of work either way but the government did not use an open bidding process as is usual.
No doubt M$ wishes other countries did the same. Some do and some don’t. In many places the project must be opened for tenders if over a certain amount which this one probably would have triggered. There may be an appeal to a higher court and there could be a referendum if enough taxpayers revolt over the prospect of M$ making sweet secret deals with their government.
