Wonder why when Microsoft was caught editing the Wiki entry about the 360 failures, slating Apple and offering people money to change there wiki articles about Microsoft no one bothered posting? Is this any less crass than the PS3 launch when Microsoft employees went around handing out Xbox chairs to people waiting in line or having a barge sale past the TV cameras with Xbox live Posters all over it at the Paris launch party. That was quite amusing in a way, sad but quite funny bit like the Wiki entry.
The MS changes, like the Apple ones or the Sony Blu-ray ones are not directly relevent to a 'console gaming' forum.
The MS PR stunts were just that, open PR stunts; nothing was underground. I'd rank Sonys idea to release the Killzone 2 demo the same day as Halo 3 is launched (http://www.n4g.com/News-64784.aspx) the same as MS sailing past the Paris Sony PS3 launch with a banner saying "Xbox 360 heart you". It's an open and honest PR stunt; publically orchestrated to deflect attention.
As I've said I don't think this is a big issue, it's just a bit embarassing for Sony and something they'll probably (should) end up publically apologise for.
