Here’s a radio interview BoomTown did earlier this week on San Francisco’s KQED “Forum” show, hosted by Michael Krasny.

The topic was a report in the The Wall Street Journal that certain third-party apps on Facebook were grabbing information about users in ways that violated the social networking site’s privacy guidelines.

Privacy advocates cried foul, while others thought it was more a tempest in a teapot– which I, NPR reporter Laura Sydell and Marc Rotenberg, executive director for the Electronic Privacy Information Center, discussed.

One conclusion, which you will understand after listening: Facebook definitely does not cause cancer.

Here’s the audio:

With its admission last week that its Street View cars unwittingly captured data sent over unsecured wireless Wi-Fi networks, Google (GOOG) appears to have run afoul of regulators on both sides of the Atlantic.

Sources familiar with the matter tell the Financial Times that the Federal Trade Commission is considering an inquiry into the matter, and the panel of European privacy regulators that advises the European Commission is calling for a full investigation to determine exactly what information was collected and whether the manner of its collection was a violation of privacy law.

The Europeans seem particularly miffed over the cock-up and Google’s explanation for it, which they find a bit suspect. Over the weekend, Peter Schaar, Germany’s federal commissioner for data protection and freedom of information, fired off a caustic blog post questioning the credibility of the company’s claim that personal data were collected accidentally.

“So everything was a simple oversight, a software error!” Schaar wrote. “The data was collected and stored against the will of the project’s managers and other managers at Google. If we follow this logic further, this means: The software was installed and used without being properly tested beforehand. Billions of bits of data were mistakenly collected, without anyone in Google noticing it, including Google’s own internal data protection managers, who two weeks ago were defending to us the company’s internal data protection practices.”

Have to admit, he does have a point. How does a company with Google’s smarts and technological acumen collect and store Wi-Fi network payload data in more than 30 countries for three years without being aware of it?

Mistakes are made, I suppose. But the breadth of this one is pretty incredible. As Marc Rotenberg, executive director of the Electronic Privacy Information Center, told the Financial Times, “This may be one of the most massive surveillance incidents by a private corporation that has ever occurred. It is unprecedented vacuuming of WiFi data by a private company. Can you imagine what would happen if a German corporation was sending cars through Washington sucking up all this information?”

Yes, but to err is human…

It is an extraordinary market play. And an unsettling one. For it seeks to place Google (GOOG), which already collects vast amounts of data about our Internet use, at the very center of our information experience.

The privacy implications are, of course, horrendous. And while Google will inevitably dismiss such concerns as paranoid and argue that any data the company might collect at the OS level will be used only to improve its services and benefit users, it should still give us all pause. Because when it is finally launched, Chrome OS will be yet one more deep well of consumer data to which Google will have access.

There are already quite a few such wells, including Google Search and Chrome, that profile user interests and surfing habits: Gmail, which gives the company access to our email conversations, and Google Voice, which gives the company access to our spoken ones. Add to this Google Street View and Latitude, a service that tracks the physical location of its users, and mobile and desktop operating systems and, well…that kind of consolidation of Internet-based services around a single dominant company should give us all pause.

Lest we forget, Google is in the behavioral targeting business. Why would people ever use an OS developed by a company whose business is based on meticulously recording and analyzing their online behavior? Because they enjoy using its other services, I suppose. But there is a privacy-vs-ease-of-use tradeoff here. And with Chrome OS, it is unprecedented. Further, while Google might tout its “don’t be evil” motto as reason enough to trust the company with our data, there are other entities that don’t always share that sensibility. Remember, it wasn’t so long ago that the federal government tried to force Google to turn over user search data to the Justice Department…

“Competition in the OS market should always be welcome, but Google is the special case,” Marc Rotenberg, executive director of the Electronic Privacy Information Center, told Digital Daily. “It has become dominant across many essential Internet services–search, mail, video, online apps, and advertising. Coupled with Google’s growing profiles of American consumers and reluctance to adopt meaningful privacy safeguards, we expect that antitrust authorities in the US and Europe will view Google’s entry into the OS market with enormous skepticism.”

Jeff Chester, executive director of The Center for Digital Democracy, echoed Rotenberg’s concerns. “Google’s new OS has to be placed under the data collection X-Ray by US and EU privacy regulators and advocates,” he said. “Any expansion into the marketplace by either Google or Microsoft should generate intense scrutiny, especially for the privacy implications. These two are engaged in a global data collections digital arms race, which has far-reaching implications for consumers and their information.”
