Gelf Magazine has an excellent interview with Mark Cuban on why he decided to fund the Grokster defense. It avoids the traps the typical Grokster piece falls into -- for example, the suggestion that the case is about abandoning copyright law, or getting music for free, or robbing artists of their livelihood.

For instance, Cuban is asked what he thinks of Grokster, the software. His reply: "Have not used Grokster. Have no plans to." You'd get the same response from anyone at EFF, and likely the vast majority of amici. Why? Because this case isn't about filesharing software full stop. It's about preserving the environment for innovation.

Another nice myth-busting exchange:

Gelf Magazine: Does the Betamax precedent apply to the Grokster case, even though people are using digital technology like Grokster to amass libraries, not just to tape shows and enhance viewing convenience?

Mark Cuban: Yes. People amassed libraries on tape as well. You can pick up any movie-collector mag and see the ads to buy a VHS or DVD of any TV show ever made. That's a big library, and those ads have been there for at least 10 years. The industry doesn't care.
