I assume the reach of HN means more than a few people who are reading this thread are currently working with telemetry or tracking data. Yet rarely do I see any posts offering an insider's perspective of how it is used. Obviously there are privacy and ethical barriers, not to mention NDAs. But without the opposing view these discussions are always heavily slanted toward the "data collection is bad" opinion with no evidence that the data being collected is actually being used in the nefarious ways being speculated. Who will be the Snowden of the advertising industry?
