Mark Zuckerberg did just fine in his first turn in the congressional hot seat on Tuesday. He was confident. He capably tackled many of the queries proposed last week by Bloomberg columnists. The 33-year-old billionaire appeared humble throughout much of the hearing, with only a few smug smiles.

The best news for Facebook Inc. the company was that Zuckerberg ably deflected any challenges to the beating heart of its economic model: its hungry data collection and the fine-tuned targeted advertising based on that data. Zuckerberg's success is a win for anyone primarily concerned with the company's market value. But it's a loss for the rest of us.

Facebook will keep failing users' trust as long as its business is based on unrestrained hoovering of as much user data as possible and crafting ever-more innovative ways for advertisers to harness that information for commercial goals. It's an arrangement to which Facebook's users agree and can sidestep, technically, but it is hardly informed consent or a real option to avoid.
