Well since Chrome is a Google app, and Google is well known for tracking your surfing, I don't see why MSE wouldn't want to warn you that your putting your privacy at risk. I use Google search all the time but I don't use it to search stuff I don't want tracked (ixquick). And for that reason I don't think I want them to have control of my browser too. Besides I tried Chrome and I was very disappointed in its GUI. Those that love it can have it, be my guest.
