And they are quite effective. My government believes selling customer data is the road to riches. They plan to sell even patient data from mandatory governmental health services. Complete lunatics in my opinion.
If the data is truly anonymized (and that's a big if), would you still have an issue? Could you share which government is doing this? It is very troubling. Edit: thank you all for good responses, I wasn't aware of the risks of de-anonymization but I will do more research into this.
I'm not yet convinced it can be done in a way that can't trivially be reversed by anyone combining it with other datasets.
And if it can't be anonymised, then it probably shouldn't be saleable.
