Except that I would assume it would take a very large amount of time to code their own NIF packages from scratch; and I honestly doubt that legality. If I write software, and own copyright, that doesn't mean you can write identical software just because you wrote it yourself.
Yes, you can write software that does the same function. It's allowed by law, and if copyright or patents are used to prevent this, you can fight in court for it. (Not that a petty NIF tool would be fought for.) Of course, small developers don't have the money for trials, so they get the butt end of the law, as usual, but this doesn't affect Bethesda and this doesn't affect a mere NIF import tool.
Even if Beth could just code their own, I would think that would take a huge amount of time and money.
Huge? An import tool? No man, that doesn't take long and doesn't cost much. Depending on the complexity of the NIF format and features they want to import, this could rank from 40 to 200 man hours. That's cheap for any software developer, and pocket change for Bethesda.
This is only true to an extent. There are laws against creating things too similar to something else as long as it is not a fundimental design of the... thing. This is why LEGO cant copyright the brick design and why MegaBlocks fit perfectly with them. The design was rules to be fundimental to the design of the toy, and thus copyrighting it would effectivly be a monopoly.
Which is exactly the reason why you can write a program to deal with the same kind of data transformation that another program does.
Since the only thing keeping Bethesda with the Nif format is ease of use, they are still bound by many legal limitations that would prevent them from releasing much, if any information on the format structure.
I doubt it's patented, and software corporations hardly ever got in trouble for posting file format information.
Exactly. If the time investment isn't worth the gain, then they wont do it. Bethesda is a business, first and foremost, so if its not worth the cost, they have no reason to do it.
But keeping the quality mods coming is keeping free content coming to a game they sell while others develop or extend for free. Even if corporations are amoral (of course they are, and this is why they are pests but that's another topic), It's a smart business move to support people who create game content for free. (I hope you realize Bethesda see us all as idiots who work for free, even support and bugfix their game for free.) That's why they released the CK and supported it to some extent, and that's why it'd be even smarter to provide the necessary tools, unless they want mods to stick to texture replacing and sword editing.
Patents should exist, but should not be a barrier to halt progress.
Patents should exist because...? Because big corporations, that's why. Big corporations (and here I'm using "big" as in "much larger than Bethesda"), as well as patent trolls (a well-known cancer of technology and other industries) are the only ones who ever made a profit from them, the only ones who can work unencumbered by them due to their large portfolio to exchange, the only ones with the money to fight for them in court, and use them to fight their competition (rather than coming up with a better product), and the only ones who can't get really bullied with them. Patents, especially software and business method patents which is my area of expertise (though they probably are similar elsewhere) are cancer in an on itself, as few things ever harmed technological advancement as much. They hurt small developers, they prevent small developers to become large, they hurt, slow down or completely destroy competition, they are used instead of competition, and as such they are directly against users' interests. They're unfair and unrealistic as you can't prove you're the first to do do something — the first what? The first to file it? To do it privately? In your country? In this planet? What about people who already did that in their personal projects? And on top of that they are terribly implemented, piss on prior art, allow corporations to file anything and bother checking prior art only during multi-million dollar trial procedures which small developers will never be able to afford, and allow for utterly [censored] registrations (e.g. Amazon's one-click check-out) which can't be worked around, thus fueling monopoly in various sectors. Do I need to continue?
Being a member of Anonymous you should know that. Anon believes that innovators do deserve pay for their work even if it is being copied by another as recognition of such work being popular amongst consumers, but under no circumstances should the innovator be allowed to monopolise the innovation.
No, Anonymous doesn't believe in anything because it's not a group, an organization or a religion. You do. Anonymous people are not particularly aligned with patents, on the contrary, many people who work anonymously appear to be against. Nevertheless, I'm not your personal army and I'm not going to think, say or do something regardless of how loud you or anyone else would claim Anonymous does. I'm also not a member of Anonymous; when did I sign up? I'm somebody who wrote "A_for_Anonymous" in the username field, that's all. You don't understand Anonymous.
