So far as I can tell, it's not so much "The Register thinks" as "Orlowski thinks" - much though I tend to enjoy reading his articles, a small dump truck full of salt is pretty much always required.

The improvement from one star to four on the efficiency-as-a-charity thing and the innovative things they're doing with the money led me to have a more positive impression of wikipedia at the end of the article than I did beforehand; hopefully a decent percentage of readers will feel the same way.
