I don’t want to be unnecessarily Microsoft bashing here, but take a look at these two identical web searches on Google and Live Search:
First, Google (click to enlarge).
Now the same search on Windows Live Search (or whatever it’s called now):
Notice that in the Windows Live Search one, there is absolutely no mention of free software as in the freedom type. Not even a scrap of evidence that the FSF exist.
Now, either Windows Live Search is worse than I originally thought, or there’s some kind of conspiracy thing going on here. I hope for Microsoft’s sake it’s the former.
If it were the latter, I would be very worried.
It’s not Google being quirky either, Yahoo also list the FSF as the top result for the same query.
UPDATE: turns out this only happens when Live Search is set to weight UK results (like when you come from a UK-based IP address through Live.com). More info.
