Well The Register’s article does not sound anti-Wikipedia at all. In fact i would argue it’s pretty much pro-Wikipedia, since this kind of nonsensical “vandalism” (as they say in wiki land) is entirely transparent and so was possible to identify at all.

Now yogthos is pretty much anti-Wikipedia because they see it as a pro-US propaganda machine. Which is silly, you just have to read articles on Julian Assange, weapons of mass destruction in Iraq, CoIntelPro, or NSA to realize that many Wikipedia articles directly contradict US national interests and propaganda apparatus.
