Twitter has been ordered by a U.S. federal judge to turn over documents related to several people involved with WikiLeaks to the Justice Department.

Tonight, a Twitter spokeswoman responded to a request for comment on the situation:

“We’re not going to comment on specific requests, but, to help users protect their rights, it’s our policy to notify users about law enforcement and governmental requests for their information, unless we are prevented by law from doing so. We outline this policy in our law enforcement guidelines.”

In an onstage interview I did with Twitter CEO Dick Costolo at a D@CES event last night in Las Vegas, he referenced the issue, but would not give any specifics.

While he said he could not talk about WikiLeaks specifically, he indicated that he disliked government mandates to keep things quiet and reiterated Twitter’s desire to connect people with useful information.

“We’re going to lash out at things that prevent us from doing that, as aggressively as we can,” said Costolo, who also used Twitter crackdowns in China as an example.

It might be a Herculean task to fight the federal government, which is aggressively going after WikiLeaks and its founder, Julian Assange.

Some Web companies, such as eBay’s PayPal unit, have cut off WikiLeaks.

On the other hand, Twitter took legal action to unseal the court order, which allowed it to inform those involved, giving them 10 days to object. Otherwise, the San Francisco microblogging service would have had to turn over information without the knowledge of these users.

There will surely be more of these to other Web companies, with obvious candidates being Google and Facebook.

The order from the U.S. District Court for the Eastern District of Virginia is ordering Twitter to fork over subscriber names, user names, screen names, mailing addresses, residential addresses and more of several people involved with WikiLeaks.

But you can read for yourself–here is the court order, as well as the unsealing order:

Because if you’re trying to handicap the way the copyright lawsuit pans out, today’s document dump won’t do much to help you. There are revelations here, but they’re of the minor and historical variety, and I’ll get to some of them later.

No smoking gun, though. Just a lot of chest-beating and desk-thumping as both sides talk past each other.

Still, it does make for fun reading if you’re of a certain troubled mindset. If you’re not, here’s a summary:

Viacom’s case: YouTube was full of content that wasn’t supposed to be there, and both YouTube and Google knew it.

Of course they knew it! Anyone who visited the site in 2005 and 2006 knew it. The problem was what to do about it.

And that’s the most interesting part of the emails and IM exchanges Viacom has dug up: They let you watch YouTube’s co-founders, and later, Google executives, argue over the best way to keep the site growing like a weed while fending off the lawyers.

Actually, they knew the lawyers would show up eventually. “Ok man, save your meal money for some lawsuits! ;) no really, I guess we’ll just see what happens,” co-founder Chad Hurley tells partners Steve Chen and Jawed Karim via email in July 2005, as the three men decide to leave some copyrighted stuff on the site.

As as YouTube boomed, Google (GOOG) was trying to figure out how its lackluster Google Video site could compete. The big debate, according to former executive David Eun: “Whether we should relax enforcement of our copyright policies in an effort to stimulate traffic growth, despite the inevitable damage it would cause to relationships with content owners.”

Google’s eventual answer, of course, was to buy YouTube. But it went in with open eyes. A due diligence report estimated that just 10 percent of the “premium” stuff on the site was authorized.

Google’s case: Viacom–which talked about buying YouTube–was perfectly happy to use our site to market its movies and TV shows. Until it wasn’t.

Of course it was! In 2005 and 2006, all of the entertainment companies were desperately trying to get their clips in front of the site’s huge audience. Even more so at Viacom (VIA), whose youthful audience was spending lots of time on YouTube.

And the fact that Viacom executives, who had lost MySpace to Rupert Murdoch (remember when MySpace was a world-beater?), were thinking about buying YouTube–in part so Murdoch wouldn’t get it–shouldn’t be surprising, either.

Google makes a lot of the fact that Viacom “secretly” uploaded videos to YouTube, either via its employees or from marketing shops it hired. But I don’t get the impression that the “secret” uploads were supposed to dupe YouTube. I get the impression they were trying to dupe YouTube users into thinking the videos were edgy and cool.

“The goal is to make it look “hijacked,” an executive at Viacom’s Spike network told the producers of a mixed martial arts show, describing a video he gave them so that they could seed it on YouTube. The idea was to make the clip “look as though it was leaked out by production.”

Viacom’s embrace of YouTube does bolster Google’s case in one way. Google shows, fairly effectively, that Viacom’s lawyers have had a hard time figuring out which YouTube clips the company authorized. If Viacom can’t figure out what’s supposed to be on the site, Google argues, how do you expect YouTube employees to know?

So. Strip out all of the depositions, documents and emails, and we’re back to where we started. This case will hinge on the way the court decides to interpret federal copyright law.

Viacom argues that YouTube is a video version of Napster or Grokster–designed to profit from intellectual property it knows is stolen. And Google argues that it’s doing exactly what the Digital Millennium Copyright Act tells it do–asking its users to behave, hoping they do, and taking down offending clips when their owners ask them to.

So pay attention to that ruling–it’s going to be really important. But unless you’re paid to keep an eye on digital media, you can ignore most of today’s paperwork.

Piracy helped the young generation discover computers. It set off the development of the IT industry in Romania. It helped Romanians improve their creative capacity in the IT industry, which has become famous around the world. … Ten years ago, it was an investment in Romania’s friendship with Microsoft and with Bill Gates.”

– Romanian President Traian Basescu to Microsoft Chairman Bill Gates in remarks delivered at the opening of Microsoft’s Global Technology Support Center in Bucharest, Feb. 1, 2007

Like consumer OS adoption rates, piracy rates for Windows XP are much higher than for Windows Vista. And with XP scheduled to be discontinued once and for all next year, Microsoft is stepping up efforts to stem its spread through piracy. To that end, the company has declared Tuesday Oct. 21 Global Anti-Piracy Day. And to celebrate it, the company is launching a series of education and enforcement actions in 49 countries on six continents around the world. A broad initiative. So broad, in fact, that Microsoft has actually created an interactive piracy map that describes its efforts in particular countries.

That said, Microsoft (MSFT) is realistic in its goals. “Are we able to solve absolutely every problem?” asked Microsoft Director of Intellectual Property, Vanessa Hutley. “No … there are some people who will always not want to pay for something, and there are always people who will want to exploit.”
