All the answers you got show why this conversation goes badly. No one can come up with an actual problem that data collection causes, it’s all silly comparisons to giving people your credit card number or shitting in front of them.

For me, having my data collected is like having CCTV cameras in stores. Yeah, technically someone is filming everything I do. Yeah it would be bad if a private individual was filming me for nefarious reasons. But no one actually uses that data for anything bad, and it doesn’t actually cause any problems.

All that happens is I get more relevant ads.
