All a website is doing is giving me a bunch of bits for free. I can do (mostly) anything I want with those bits. I can leave them how they are, or I can modify them so that the presentation is more appealing to me. The owners of these websites understand that they cannot do anything to prevent me from modifying the way the bits are presented to me. There was no agreement between me and them that I won't modify the bits: they just send me the bits when I ask for them. A better analogy would be a pizza company that gives out free pizzas, no questions asked. However, they get money every time a customer eats an olive on the pizza. When they give me the pizza, they know very well that I can just pick off the olives (I hate olives). So I am well within my right to pick off olives. The problem is their business model, not me picking off the olives.
