Yes, but my point is it seems a jolly strange thing to do to weld, conservatively, 100 million people, including pretty much your entire state adminstration apparatus as well as the technical baseline of a very large proportion of your IT industry to a foreign proprietary OS from your biggest geopolitical rival that could be cut off by the other side in a dispute. I guess technically this actually applies to any country, but China's the obvious one where it could vaguely plausibly actually happen one day. Not basing almost your entire country's IT on Windows also doesn't preclude you participating in the software export market.
