Sommerswerd asked me to change this
Here's another example. Lets take books. Imagine in say 20 years books are avaliable only in online format and authors (producers) have the right to decide what version of the book they prefer. If Tolkien were to publish LoTR in 2030's he'd have right to say: "I don't like the way the book ends, lets change it so that Frodo dies in Mordor". As a user of "LoTR digital book" you'd have to smile and nod at every change of what you already own because of intellectual property rights. You'll no longer have the freedom to have the product as it was sold to you. Now, books are not published that way yet, why should games be? In most of services the "client is always right". Shouldn't the gamer also "be right" and have have the right to keep what he bought?
That is a rather extreme and not so good example, but yes, fair use rights are important. I don't think fair use would apply to a publisher deciding to change a part of a story, though... and I'm not really convinced that it should, either.
