I care because if companies can collect enough data to recognize patterns, and generalize those findings, it becomes everyone's problem. You don't think health insurance providers are dying to buy this data? Or drug manufacturers? You're being double sold and generalized.

For instance maybe insurance rates increase in a region showing a higher percentage of heart palpitations. I live there and now my rates increased even though I don't even own a bitfit.

I don’t use fitness trackers. I also refrain from posting negatively about products I don’t use.

Do you have any proof about FitBit selling to insurance companies? Not all companies are selling data to 3rd parties.

The burden of proof should be the other way, until then we have the right to be worried.

Was FitBit upfront about this when they sold their products though? I don't actually know the answer and I think that's a critical piece of information.

People buy fitbits to track and record their stats.

On a personal basis.

> If you don’t agree with their practices or data collection then don’t use their products.

I don't agree and don't use their products. Doesn't mean I can't call them out when they do something I don't agree with.
