For the Loyalty cards, at least you are knowingly signing onto it. There was never any incremental change, pulling back on privacy and exactly how much they look at and save what you are buying. Google, Facebook, the government and so on, decided to take your privacy without fully revealing the scope. Or, if not the scope, the amount of time that data is kept and who it is shared with. Communicating with someone on the internet shouldn’t be free reign to share my info with foreign countries, un-redacted, even if I was on board with the US looking at it, which I’m not.
I’m not on Facebook nor Twitter anymore. I pay attention to privacy notices and contact whoever is mailing the information in order to opt out of extended “sharing”. It seems that that is never a default. I have put freezes and fraud alerts on Credit reporting agencies because they are sharing a ton of your financial information with companies without your knowledge and sometimes they share that information with ID thieves*, see Experian.
