Software Customer Bill of Rights

Cem Kaner has written a Software Customer Bill of Rights. His general approach is to require that customers have roughly the same rights when they buy software as when they buy other products.

Much of what Kaner says makes sense. But at least one of his principles seems awfully hard to implement in practice:

2. Disclose known defects. The software company or service provider must disclose the defects that it knows about to potential customers, in a way that is likely to be understood by a typical member of the market for that product or service.

This is hard to implement because software products have so many defects – big mass-market software products typically have thousands of known defects. And this is not just the practice of one or two companies; it’s standard in the industry. If a vendors waited until all the defects were removed from a product, that product would never be finished and would never ship.

Some of the defects in software products are serious, but most are relatively minor. There is simply no way to explain them all to consumers. And sometimes it can be hard to tell in advance which defects will prove to be critical to customers.

Still, Kaner seems to be on the right track. It would be helpful if vendors disclosed the most serious known defects to their customers, so that customers could weight their impact in deciding which product to buy.

Business Week Interview

Business Week Online is running an interview with me, done by reporter Heather Green.

Comments

I’m thinking about turning on the Comments feature, so that readers can react to my postings right here on the site. So far I haven’t allowed comments, because I prefer to get reader input by email; and I’m happy (at least in theory) to write followup posts that incorporate and react to reader comments. Lately, though, I have come to appreciate the comments feature on other blogs, so I’m thinking about using it myself.

Please give me your input on this issue. I have turned on Comments for this posting so you can do so.

Trade Secrets and Free Speech

Yesterday the California Supreme Court issued its ruling in DVDCCA v. Bunner, a case pitting trade secrets against freedom of speech. The court ruled that an injunction against disclosure of a trade secret is valid, even though it restricts some speech.

The case relates to CSS, the encryption scheme used to scramble the data on DVDs. CSS was developed in secret, and an outfit called the DVD Copy Control Association (DVDCCA) claims that the details of CSS are its trade secret. Andrew Bunner posted DeCSS, a program that unscrambles CSS-encrypted content, on his web site. DVDCCA sued Bunner for misappropriating its trade secret. A lower court issued an injunction, ordering Bunner not to publish DeCSS. Bunner appealed, arguing that the injunction violated his free speech right.

The lower court ruled that Bunner knew (or should have known) that CSS was a trade secret, and that Bunner knew (or should have known) that the original source of DeCSS had gotten the trade secret improperly. I think these factual findings were highly questionable, but the Court accepted them for the purposes of its decision. So the issue before the state Supreme Court was merely whether an injunction against publishing a trade secret violates freedom of speech. The Court ruled that it does not, at least not when the speech is software code.

Why does it matter that the speech is software code? As Seth Finkelstein points out, the Court seemed to say that software code cannot be of public concern, because only experts can read it:

DVD CCA’s trade secrets in the CSS technology are not publicly available and convey only technical information about the method used by specific private entities to protect their intellectual property. Bunner posted these secrets in the form of DeCSS on the Internet so Linux users could enjoy and use DVD’s and so others could improve the functional capabilities of DeCSS. He did not post them to comment on any public issue or to participate in any public debate. Indeed, only computer encryption enthusiasts are likely to have an interest in the expressive content– rather than the uses–of DVD CCA’s trade secrets. (See Tien, Publishing Software as a Speech Act, supra, 15 Berkeley Tech. L.J. at pp. 662-663 [“Programming languages provide the best means for communicating highly technical ideas–such as mathematical concepts–within the community of computer scientists and programmers”].) Thus, these trade secrets, as disclosed by Bunner, address matters of purely private concern and not matters of public importance. …

This seems like a pretty odd position to take. Information about Enron’s finances is of public concern, even though only accountants can interpret it in its raw form. Information about the Space Shuttle wing structure is of public concern, even though only a few engineers understand it fully. CSS is a controversial technology, and information about how it works is directly relevant to the debate about it. True, many people who are interested in the debate will have to rely on experts to explain the relevant parts of DeCSS to them; but the same is true of Enron’s accounting or the Shuttle’s engineering.

Odder still, in my view, is the notion that because DeCSS is directly useful to members of the public, it is somehow of less public concern than a purely theoretical discussion would be. It seems to me that the First Amendment protects speech precisely because the speech may have an effect on what people think and how they act. To suppress speech because of its impact seems to defeat the very purpose of the free speech guarantee.

It's Ten O'Clock. Do You Know What Your Computer is Doing?

Last week saw a scary story about a British man who was acquitted of the charge of possessing child pr0n. [Deliberate misspelling to keep dumb censorware tools from blocking this site. But some censorware programs will block this anyway. Heavy Sigh.] The illegal material was on the man’s computer, but he argued that an intruder had put it there, and he presented evidence to support that defense.

Although I have no special knowledge of his particular case, I know the kind of scenario he described does really happen. At least two innocent people I know have had their computers turned by intruders into pr0n distributors.

The lesson of these incidents is that we have less control over our computers than we have over our physical territory. Nobody would turn a file drawer in your office into a distribution center for contraband; but they might do that to your computer. Inevitably, innocent people will be accused of crimes, and they will suffer, even if they are eventually acquitted. And of course, some real bad guys will get away with crimes by blaming them on nonexistent intruders.

The best way to address this kind of problem is to make sure that people retain control – in practice as well as in theory – over their own computers. When we erode that control, whether we do so by technical or legal means, we are making the bad guys’ jobs easier.
