Revtim, there is the question of who’s backyard are you playing in? Even if you don’t plan on making money on it, you are still using someone elses creations. Often, if they don’t say no, they are considered giving tacit approval. Look at Trademark requirements for example, I’ll be the first to agree that many companies go overboard in protection of their trademarks (Just try starting a company that uses the ‘r us’ moniker, for instance…Toys ‘R’ Us is famous for their lack of humor there.) But if they don’t protect them, the implicit understanding is that they loose them.
Now, why should this be important? Well, for one thing, they have no control over what the fan writes. An example of this is talked about in the foreword to Man-Kzin Wars, where Larry Niven explains why he doesn’t allow fanfic anymore. Basically, someone wrote porn using his creations, so no no-one can use them without his permission, profit or not…Its his creation, he gets to decide that.
I’ll try to give an example, you are a programmer, and you come up with a neat little program that will compute various energy state equasions, quickly and without much difficulty. You put it on your internet site as an example of what you can do, and the goverment takes your program and starts to use it to help build more powerfull nukes. By your reasoning, since the Goverment is nonprofit, they can use your creation as they see fit, even if you yourself were antinuke. You have no control over your creation, and that is why Fanfic is illegal, because the owner of the creation should always have control over their creations.
