Windows XP launched more than 10 years ago. What I said was true for Vista (5 years old) and 7 (2 years old) and is true for Windows 8 afaik. I'm not sure what your point would be - that you'd pirate Windows 8 because you didn't approve of the ease of use of an activation system they deprecated 5 years ago?
Why should he/she approve of the system that makes his legally licensed software not work just because it's 5 years old? If it didn't have the license activation anti-feature, it would work just as well now as it did 5 years ago.
Because the blog was titled "I'm pirating the Next Version of Windows" (because I feel it will be too difficult to activate) and not "I'm pirating Windows XP"
