While I broadly agree, there is plenty of precedent for not asking informed consent. Banks sell your credit card data, which is very easily de-anonymisable. Insurers price policies for you based on their previous clients data, and will use yours for the future clients too. Any loyalty program with a customer ID mines the hell out of your data. You probably agree to all of these; somewhere on page 23 of the contract. I’m not saying it’s good, only that I get don’t follow academic guidelines either, with impunity.
