I doubt it - there are other sites springing up which are quite anti PWC because they're doing layoffs at the moment. It's also registered to an individual and the whole thing just reeks of a "sucks" site. In a sense it does raise the profile of PWC's name change, but I seriously doubt they've engineered it. The Lone Gunmen might well think otherwise
I find it far more plausible that someone in the US arm was responsible for getting the domain names for the change and was just totally ignorant of the existence of regional domain names, and so neglected to get hold of them. This isn't the first time PWC have had domain name issues either, they tried to get PWC.com off someone but failed to do so...Spin or not - the new name's still a donkey!
