Microsoft "clarified" the position to Polygon:
Update: A Microsoft spokesperson clarified in a statement to Polygon that the upgrade to Windows 10 will "not change the genuine state of the license," meaning non-genuine copies of the operating system will continue to be non-genuine.
The consumer free upgrade offer for Windows 10 applies to qualified new and existing devices running Windows 7, Windows 8.1 and Windows Phone 8.1. Some editions are excluded from the consumer free upgrade — including Windows 7 Enterprise, Windows 8/8.1 Enterprise, and Windows RT/RT 8.1. Active Software Assurance customers in volume licensing have the benefit to upgrade to other Windows 10 enterprise offerings.
We have always been committed to ensuring that customers have the best Windows experience possible. With Windows 10, although non-Genuine PCs may be able to upgrade to Windows 10, the upgrade will not change the genuine state of the license. Non-Genuine Windows is not published by Microsoft. It is not properly licensed, or supported by Microsoft or a trusted partner. If a device was considered non-genuine or mislicensed prior to the upgrade, that device will continue to be considered non-genuine or mislicensed after the upgrade. According to industry experts, use of pirated software, including Non-Genuine Windows, results in a higher risk of malware, fraud (identity theft, credit card theft, etc), public exposure of your personal information, and a higher risk for poor performance or feature malfunctions.
So in fact there is no change whatsoever.
What Microsoft says now is that Chinese pirated Windows will continue to be pirated Windows; the only really big news here is that Microsoft helps the pirates by telling them that it will be possible to update the pirated Windows 7 or 8 to a pirated Windows 10.
So in other words Microsoft is telling the Chinese market that it will be possible to pirate Windows 10 too - why does Microsoft have the urge to communicate this?
Better with a pirated Windows than a legal Linux?
higher risk for poor performance or feature malfunctions
Microsoft will probably be in a position to create the feature malfunctions and poor performance after a zillion Chinese have become used to Windows 10.
Make them Junkies first - then it is time to collect ?
