Nobody is saying that the technology is creepy. It's the fact that it's not at all private that's creepy.
As Uncle Ben said, "With great power comes responsibility." It's an awesome thing to have the power of "big data" to analyze your life and make better decisions. But "big data" needs to be responsible in how they handle that data (and their users' trust).
That's the whole point. The fact that they have this data means that they could share it with whoever they want, whenever they want. And we would never know. So in this particular case, it's not a data issue - it's a trust issue.
The Jawbone device is built upon the idea of the company storing the information. It is implicitly implied that if you use the device your data is being stored somewhere because that is what you are paying for them to do
Sure - but that's not the issue that people have with this. The issue is that Jawbone decided to release personal data (aggregated, but still personal) to people who did not own the data.
Like I said above. . . it's not a data issue. It's a trust issue.
