While you're right that SAA cases are notoriously hard to prove, I simply don't think that Microsoft would even attempt something touching anything in that space given their history. And the act was initially created in order to level the playing field to encourage fair competition. It does not seem farfetched for someone to argue that by using its immense resources to sweep Fox out of Google's index, Microsoft is engaging in unfair competition. This is the specific type of anticompetitive action the Sherman Act was enacted to prevent. While it's true this probably wouldn't go anywhere without them getting to a point where they have a majority market share in search, this is a slippery slope and one I still think they won't go down, even if the viability of an antitrust case is low. Can't argue that getting everything Fox off of Google would be fantastic, but the greater trend of fighting financially for search indexing would snowball into a huge mess. Imagine if you had to go to Bing to find stuff on Fox, Google for CNN, and Yahoo for BBC? The internet as we know it would start to fall apart.
