I don’t think it’s wrong for shops to offer a simple, optional reward program (spend x amount, get y discount) as an incentive to shop there. Often you can enter a fake name and temporary email address or email alias (simplelogin.io has a free plan for aliases).
It’s excessive data collection for targeting advertising, the push to install apps, and dynamic pricing which I strongly oppose, especially when there is a lack of transparency surrounding it.




Yes, analytics aren’t inherently bad. They can be helpful in planning inventory and improving services like you said, but that can be accomplished with anonymized data.
The problems arise when more data is collected than is necessary to make helpful business decisions, when highly specific individual profiles and digital footprints are created, and when the data is shared with third parties who can use it for purposes other than the ones listed by who you first gave them to.
