That is the point - if SIFT is patented (though it is free for research it is not clear that Yahoo got commercial licensing) it is prohibited to generate their keypoints, even if it is to compare to your own! Just because they don't prosecute, doesn't mean it is OK. I guess in this case, Yahoo might have taken the heat for you. Hopefully they got a proper license agreement, as that would be great for everyone.
