Idea being, that if you want to automatically follow updates of a source (to be just like RSS and not manual), you have to "Like" or "Follow" them on Facebook and Twitter respectively, and then they know who's reading, no matter how many no-script and private mode you apply. FB and Twitter on the other hand shares who else you are liking or following so there you go. With RSS they have no such information.
