This is certainly much less significant then giving preferential page rank. Google controls what over two thirds of people see through search. If it doesn't appear on the first 3 pages of a Google search, exposure is very limited.
It's a shame that my original comment got voted down (didn't even know you could do that). I'd rather people share their opinions rather then voting down; the topic is worthy of discussion.
I really don't mind bundled software either. In fact, I don't mind preferential treatment being given to Knol. What I do mind is Google opening itself up to a lawsuit. A significant lawsuit against Google would have large negative effects in my opinion. I'd just like Google to show a little bit more discretion.
